¡¡¡THANKS FOR WATCHING!!!
I do not own any of the music used in this video. - วิทยาศาสตร์และเทคโนโลยี
I had no idea that compounds like limonene, eucalyptol and camphor were found in lavender oil! makes sense now when I think of the scent. Great video!!
Yeah, it happens to me too.
Essential oils are always mixtures of lots of compunds. Even with lavender oils: the method of extraction, the species of plant you use all kind of things will influence the final composition and that makes really difficult to a pair of different lavender oils have the same composition.
Particulary I was amazed with the main component of the oil, linalyl butyrate. I have synthetized butyric acid, wich smells terrible (like vomit, I promise you, real vomit :D). In the oil it is in the form of an esther with linalyl alcohol but if you smell lavender oil , somehow, you can notice the presence of that smell.
Thanks for commenting¡¡¡
@@Glattuh what is the name of the beginning track???
Normal Distillation of Lavender does not include adding other chemical compounds this is call adulteration which is bad to do! This video is a bad example of distillation of Lavender! If you have to add chemicals then you are not getting real Lavender Essential Oil. This person does this to everything they make!
Your videos are highly professional and very nicely edited, thanks. Please share video of distillation of roses
Thanks!!! Im sure I will do in the future !!!
I'm loving these sciency vids. I've tried making a few experiments in my kitchen with lemongrass, cinnamon and cardamon. I used a pressure cooker set up. I definitely need to upgrade my equipment and skills. 😳
Thanks for posting these videos 😊 Your channel is good . I am just learning more and more here! You're awesome!
Thank you very much!!
I love your videos, thank you, i'm a new sub. So much flowers for so few essential oil! Very satisfying video, you teach me great things, thank you !
Thank you so much!!! Welcome to my channel :D
This was absolutely legit! Thank you!!
Thank you for watching!
Interesting video, another interesting fact because I grow lavender. For 1 L of lavender oil you need about 55 kg of fresh flowers, with distillation we get with lavender oil a tonic that is great for skin care
Excelente video !!
Great video, keep em coming! :)
Thank you!!! It seems like steam distillations are becoming my favourite lab technique ;)
This is like a G rated Breaking Bad
I use a fractionating column and the first fractions should be the pure essential oil plus a little bit of water. No need for DCM or hexane.
Good job!
Thank-you!
Nice to see someone else who lets the material sit in the water instead of just having the steam pass through it.
People usually gets mad when I call this steam distillation too haha. Thanks for the comment
keep up the good work!!
Thank you!! New videos incoming soon ;D
Anyway i have interest to make different flowers essential oil. In my village very good fragrant flowers that cant imagine.
Two questions:
what temperature do you heat the vapor to in the head for lavender distillation?
Could you not use only Hexane and omit the DCM for the purpose of separation and final evaporation to achieve the result?
Yup , that is why i pay so much for my lavender oil😂
how much?
Hi! I like ur videos!! Great job! Could u please tell me how did u calculate the other components in lavender oil?
Thank you!
watching you from turkey, thanks for subs
Thank you for watching!
...thanks

Hi nice video,
I have a question how to know that how many days it takes for all the solvent to evaporate leaving behind only a concentrated extract of essential oil?
Muy bueno
Gracias!
that's for the hair shampoo to make the hair shine and smoother.
I'm very curious as to why you resulted with 25% ocimene and 43.73% Linalyl Butyrate! That is unlike any lavender composition I've ever seen. I have read that temperature, distillation time, and also hydrodilstilation vs steam distillation all can affect the % of constituents in the resulting oil. Also you hydro distilled, not steam distilled in this video. Have you looked at other lavender oil compositions? Why do you think you got the results that you did? Thanks!
Good work Sir/mam, but why did you add only 5mL MDC (you say it DCM) at first time? I assume if you would have added 12-15 mL at each time only MDC then you might have not needed hexane. Correct me if I'm wrong. And have you tried extraction with Ethyl acetate instead of MDC? Which research paper or article did you prefer? Questions from curiosity please don't mind 😊
I am NOT putting dichloromethane in my kitchen man, and last I checked hexane was pretty hard to come by so I guess its back to the drawing board with my ambition of becoming the essential oil baron on this side of the mississippi.
Well that put me right off having a go myself. I think I will just be buying it instead!
When you say "drop the stirring rod" is it just tiny glass rod you bought to drop into flasks? I keep googling mini glass stirring rods and nothing of the sorts is really coming up.
No. Dont confuse it. There are glass stir rod, wich are used to stir things manually, and magnetic stirring rod. This are magnets that are covered normally with PTFE (and is the white thing you see in the video) and are used to stir things automatically with a stirrer, wich normally has the advantage of having a hot plate. Glass stir rods are pretty cheap, while magnets are normally more expensive. I think chemistry would not be chemistry if stirrers were not invented :P
Check out this video th-cam.com/video/3aq8iJUpW5w/w-d-xo.html at 2:55. There you can see a stir rod working properly :D
Great video! Being new to this, I have a question. Can you freeze the fresh picked flowers to be processed later or will that damage them?
Hi ,thanks a lottt!! Well, in my opinion it is better to freeze them if you are not able to inmediatly extract the oil. I think cold wull not damage the compounds in it no ;D
هو بيحط اي
Every time i make organic lavender tea I just let the steam go over my face while I wait for it to cool down lol feels relaxing💯dose that do anything at all???
I dont really know anything about EO and its effects on the body (my biochemistry knowledge is poor D:), but I've always heard it is recommended to do that when you have a cold and so.
Search something like effects of lavender essential oils in the organism, or somehting like that, im sure you will find something ;D
Thanks for commenting¡
Wat is better distill lavenderoil or via soxhlet?
Hello, thank you very much for this video! I was wondering if you would be able to suggest the best place to buy the equipment required for the setup shown in the video above? Would you have a list of equipment name too?
Hi! Thanks for watching me! If you see my latest video you will find a link to my sponsor web for the distillation apparatus I used. It is some serious quality stuff, I am proud to work with them! Feel free to check the video description there. If you need something in particular just tell me, i can talk to my sponsor for whatever you are interested in!
@@Glattuh Ah I see, I did go to their website. I am actually looking for a setup for the steam distillation setup components for the lavender extraction video, I can browse through to find the individual components for sure, but it would be nice if you could also ask what would be the cost like for the setup as a whole package?
Sry I thought that conversation was closed. You mean that the organic kit of my sponsor contain things that you will not be using for distillation? If so, I can talk to them to launch a small steam distillation apparatus, with the less things needed in order to do it. If you are interested just tell me ;D
Hello!
I carried out my laboratory in my garage to extract essential oils. I am currently working with turmeric. I was wondering if you can make a video related to turmeric, so it would help me a lot with the methodology, the extraction processes and solvents.
Thank you
I have a few videos involving turmeric extraction coming up yeah. But at this moment I am struggling with PC sofwtare and editing issues. You will have a to wait a bit more :D
you can extract curcuminoids from turmeric with pure (undenatured) alcohol at room temperature for a couple of days. Try it in milk!
Could you please tell me what is the purpose you're trying to reach with L/L Extraction from EO/Hydrosol using hexane/DCM ? I mean you could have easily seperated the two with a pipette.
Abdelheq KEHALI some EO is remaining in water
@@emilioalbar.7624 Wouldn't that affect the purity and quality of the oil?
what about removing the water under a vacuum instead.
@@abdelhak4671you do either a steam distillation or a solvent extraction.
@@taattataattataattata you'd loose much rather the oils
Would the yield be higher if you substituted the water with an organic solvent in a sohxlet extractor then distilling it off later?
Hi! Well, that is something I could definetely try one day yes. It is much more expensive and time consuming though. Steam distillation is always the best choice in my opinion, in terms of simplicity.
Thanks for commenting
Plz make essential oil from tulsi (holy basil)
Me gustan mucho tus videos,
consulta...el hexano es muy tóxico, difícil de adquirir y costoso, que otro solvente se puede utilizar como reemplazo?
No es necesario usar ningun disolvente pero algunas alternativas son el dietil eter y el acetato de etilo. Pasate por mi ultimo video, ahi verás que no he utilizado ningun disolvente, lo cual es perfecto cuando se trabaja con mayores cantidades. Aqui lo he usado por que tenia a mano hexano y por arrastrar todo el aceite esencial posible.
Can i know what is the boiling point of the lavender oil?
Thank you for sharing! If the oils are already visibly separating from the water, why use the other solvents?
Hi thanks! I babe been asked this a lot. Maybe I should post a FAQ comment or something haha. I used solvents because i just wanted to get all of the oil that could remain stuck to the glassware. I had solvents at that moment so it was easy for me to do that ;)
Thanks for watching
This is adulteration of the oil. Having patience and wait for the oil to drip off the glass is key. Then visibly separate from the water. No need for adding chemicals.
@@Glattuh is using solvents reduce the oil quality??? is there any side effects???
I would not buy any oil that was extracted with methylene chloride. I realize it slightly improves the yield.
Hi
Can you list out the name of the components and where to get them from please ?
Thanks
Hi¡¡ That is just a normal chemistry distillation apparatus. It is meant to be used in the lab but it works with essential oils too¡¡¡ You can find them and more specific essential oil distiller on ebay for example ;D I got mine at labbox.com
Hello! Thanks for the video! Why do we have to use distilled water?
Its better to use distilled water because tap water contains active chlorine and other salts that may affect the extraction process
I would like to know the heat setting😮
Hey man, I have some questions. What temperature did you use and how did you let the solution evaporate in the end?
For the steam distillation I just apply high heat. The temperature will never rise much more than 100ºC so you dont have to care a lot. For the hexane very little as it is already really volatile.
@@Glattuh Thanks mate, cheers from Brasil.
Where would someone be able to buy the equipment used in this video
Ebay and Amazon, search for "essential oil steam-distillation kit.
This method won't leave me with hydrosol?! Just the oil.
If I want to get hydrosol and oil I just separate them and then I don't have to do the extraction, right?
Yeah¡ There may be a very poor ammount dissolved in the aqueous phase but you can separate them and use it afterwards¡¡¡ Depending on the oil you can get more compounds in you aqueous solution. For example with cinnamon or cloves ;D
Hello can i do this with the soxhlet all the same excluding the alcohol thankyou
You can use other solvents but not water. Soxhlet does not use steam distillation, just normal distribution of chemical compounds in 2 different phases (solid (the matrix) and liquid/the solvent))
so how much would a setup cost with all the screws and claps and so on, just a ballpark number would be nice. my girl is into these oils but the cost so much. I thought maybe I can grow most of the ingredients myself?
The whole kit cost about 150€ including many things. For example I made the stand bymyself so... it is a very aprox cost. And yes, you absolutely can grow lavender by yourself. It is very used in parks and gardens :) And when talking about essential oils there is an endless list of things to extract (lemon, orange, roses, ginger, woods, resins...)
What is the music from intro
I have a question , at last step you kept the essential oil bottle open ? So that other chemicals will evaporate and only lavender oil will be left ? (Does lavender oil evaporate while doing this ?)
Some of the more volatile compounds in the EO will evaporate too, but that is minor. I do not think it will affect the final product, at least for what a human nose sensitivity concerns
Hi,
I'm working on essential extraction of lavender oil. I followed your method but I have a question. How long does it take for the organic solvent to evaporate?
It depends on how much volume yopu have and also temperature and even airflow. So I do not really have an answer for you... I must say that ideally no solvent should be used as lavender EO separates easily from water and decantation is pretty straightforward :D
I have a video where I show that no solvent is needed here: th-cam.com/video/NlgZACkf3Q4/w-d-xo.html&ab_channel=NationOfOurHobbies
@@Glattuh what is the best temperature to extract the lavender EO? Thank you
If we use copper instruments? Coz these glass are delicate.
In theory copper does not affect the result but as a chemist myself... I prefer glass. Much more inert. This is a very simple set up though, I can guarantee that a copper one will be much more difficult to get, to clean and also more expensive ;D
I can't find property gloves. What do I do now?
You dont really need them if you dont use solvents. Try to extract a larger ammount of lavender so that separation of oil phase from water is easier and hexane and/or DCM are not needed. In this case you can use the EO for making soap for example :D
How do you make an oil for woodsy scents! Tree bark? 😂 I’m curious to know, pls upload a video about it!
No joking, literally tree bark. Easiest example, cinammon is literally powdered tree bark :D
@@Glattuh 😂 that’s so cool! Video pls when you get the chance :)
How much essential oil can be obtained from a 500ml Boiling Flask?
hi, why cannot we heat up to evaporate the hexane and DCM instead of waiting for days? Most of the chemicals present in the extract (as you mention them) seem to be big enough as to have higher boiling points than the solvents and from sight I imagine they should be stable. Awesome tutorial by the way
Yes! In fact I did it in another video, with lemon essential oil. In any case rapid heaing may degrade the essential oil, and it can also loss a bit of mass in the process even if the boiling points are high, as the compounds are volatile.
@@Glattuh true, I watched the video. Just missing a couple flasks and then I will be all ready to go. Thanks again for sharing the knowledge. Would be great to see some more natural product extractions in your channel
kaç dereceye kadar ısıtıyoruz?
I really didnt see , when you put stir rod ....???
Which model stir rod ..
How if i dont have or didnt use stir rod
1:35
It just help to give the liquid a small stir. With that much vegetal material it is not necessary if you dont have one. Bubbles will came out of the raw material, without causing splashes
Are you sure that not distilled water can be used? I heard otherwise from every other video/article
Ideally distilled water should be used yeah, as tap water contains sources of chlorine that can degrade the organic compounds. But I guess the concentration is too low to make a huge effect. It will also react with other materials apart from the EO, like the peels and so on... as said, i wont say it has too much of an impact at a household level
Is the DCM and Hexane really needed? Are there other, more readily available alternatives?
Hi. No it is not needed. I used it because I wanted to recorver ALL of the oil I extracted. If you just decant the layers some of the oil will remain in the glass ware. There are a few alternatives, much less toxic than DCM and Hexane. If you want you can use ethylacetate or heptane ;D
Thanks fo commenting
Thanks for your help!
1:13 I've seen that scene before XD
Where? Don understand :D
Nation Of Our Hobbies It was a stupid joke. The flowers weren't quite as purple as one might expect, so it looks like a drug. Don't do drugs, I was just making a joke XD
:D
Can yu guide me. And i need whole set of instruments with study books. But i need training also. Can yu help me?
Secondly after making such precious essential oil who will buy from us? What r the uses? one i know making itr.
So can yu guide me how to arrange and i need training.
name of the starting track...please
why use hex stuff don't you just need to separate the water and that is it?
Blunted &co. Some EO is remaining in water
1:10 That looks like a big box of spider mummies.
If you want to use the oil you can't use these harmful solvents. you'll always have a residue of them in your product.
Agreed
as you put the lavender in the water and boiled it, it's not technically steam distillation, is it? Typically steam distillation keeps the water separate from the material, and only steam travels through the material.
Hi! Please watch my latest video about lemons and read the FAQ in the description box, the answer is there alrdy :D
why do you use Hexane and DCM? water and oil should separate themselves, right?
there is no need for adding any chemical the oil and water separates just fine. This guy is creating adulterated Essential oils.
higher yield probably because the flowers were a bit dry
Kind of yeah. If flower get dry more essential oil content but I reming you essential oil evaporates too so... Not so easy answer for that !
When you left the vial’s cap open to evaporate the solutions, doesnt essential oil also evaporate?
To some extent, yes. Depending on the type of essential oil the evaporation may be slower or faster but yes, little scent can be lost. It still smells like lavender so it was not a problem for me.
Pls sir,make ylang ylang oil
Show jasmine and tube rose
Can this oil be used on skin as you used hexan to seperate oil
Well, as I used hexane... It is not meant for beeing used not. But even if I dont im not very sure you can directly use it on the skin. It is quite irritant for both skin and eye.
is this like a soxhlet extractor water instead of alcohol ?
Hello nad thank for asking. This is another type of extraction. In the Soxhlet extraction the solvent comes in contact with the material to be extracted so it can disolve the compound or compounds you want to extract. In steam distillation water does not dissolve the essential oil. It forms and azeotrope with it in the gas form and then as it is condensed back to liquid, EO separates from it forming a different phase, usually seen as a layer above the water (as EO tends to be less dense than water)
@@Glattuh Thank you very much for your prompt reply...which of both ways are safer for consumption(if the extracted material is to be ingested ) and which way is more efficient in extracting and should give a higher yeild please.
@@goonygoogoo2 Steam distillation is better when the product is going to be used by humans. Soxhlet has more yield but you will also extract lots of different things, so do not recomment that for EO extractions, as the steam distillation is much easier and cheap. Soxhlet is more for other purposes like in analysis.
@@Glattuh so I can extract capsaicin using soxhlet apparatus but instead of alcohol I put water ?
I doubt you can do it with water as capsaicin is not soluble in it! For caipsicinoids things like alcohols or ether, which will extract other things too, so you will need purification after that, if you want pure capsaicin. If not you will get what is called an extract. Not so easy extraction if you want 100% pure capsaicins ;)
The stems have A LOT of oil in them
Hello, can you extract essential oils with a Soxhlet extraction? I was planning to use mint and hexane as solvent
+Marcela Gutierrez Hi!!! Well you can of course. At this moment im not sure if hexane is the best choice to extract mint oil because I dont know what it contains. As far as I can remember one of the major compounds in mint is menthol wich is an alcohol and im not sure it can be dissolved in hexane. Apart from that, whatever solvent you use, the soxhlet method will extract more things, depending on the solvent, such carotenes, xanthophyls and chlorophyll and many other vegetal stuff I cant imagine now. So yes you will have your extract, very coloured with those components with the smell of mint. I remember trying to extract oil from mint one time and its yield was very poor. I think the best method is to steam distill it in a large flask.
On the other hand you can first extract it with the Soxhlet and then steam distill the extract. Im sure it will give you only your esssential oil, separated from the rest of the extract.
Un saludo :D
Thanks for answering! So I can use the method shown on your walnut oil extraction video and extract the oil from the mint? Maybe trying a different solvent. Also, is it necesary to add any kind of oil before the Soxhlet extraction? Because I saw a video were the students left the mint leaves on a glass bottle with oil for a couple of days first
Yes of course but remember that you will have many other things in your extract, not only mint essential oil, and that will probably add a vegetable aroma to your desired minty smelling liquid.
Adding oil is another way to extract essential compounds. You put the material in oil for some time, the compounds difuses into the oil (and by oil I mean triglycerides, not essential "oil") and then you steam distill the EO from the oil somehow. Im not very familiarised with this method, I would have to investigate a bit more but I really think the best way is to directly steam distill your mint.
If you want to use the Soxhlet extractor remember you will have tiny ammount of good aroma compunds compared to the ammount of other things such what I said earlier, carotenes, chlorophyills and many other stuff. Imagine how vast the diversity is in terms of molecules present in a plant! ¿How many of them will be extracted in the Soxhlet apparatus? I only can imagine that you will have your flask full of really strong green liquid, good smelling but also like vegetable soup, and decolorised leaves of mint in the extractor hahaha
Thanks for commenting ;D
Can using hexane
could u distill the green nasty soxhlet gunk under vacuum hahaha :D
The floral water i get is brown and i see you get no coloration in you distilled water. What i am doing wrong? Too much hot maybe??
That is a thing that never happened to me but it may be overheating yes. Did you observed the apparatus in the whole process? If not, maybe vigorous bubbling may occured there, so it passes through the whole apparatus
Nation Of Our Hobbies yes thats posible i think, thanks a lot
Nation Of Our Hobbies is there an specific moment during the year when is better get the plant? Because i distilled 2 ballons of 2 litters each and i couldn’t get a droop
You added more water was it hot? Isnt it dangerous to add water while in process?
Hi! It was just ambient temperature water. It is not dangerous because the water below is already boiling
Nation Of Our Hobbies can mixing waters of different temperatures lead to cracking of glass flask
If it's normal glass yeah. If it's borosilicate, then no. Probably not.
@@anitachaudhary5827YES in fact it will!. arrg!
@@pluronic123 LOL I have seen Crack and exploding face occur with people who do this. Yikes!
Hey does anyone know how to break extract fragrance/oil from mango ? To get a great smelling fragrance
Maybe fruit juices can be water distilled to get some EO, but i have never tried that. Maybe in a future video I can give it a try :D
Nation Of Our Hobbies do you know any place I can get natural mango extact ?
isnt this hydrodistillation? steam distillation is when the flower is not submerged in water and its a high pressure closed sistem.
Can we use heptane instead of hexane?
Hi¡¡ Absolutely¡ In fact is a better choice cause its trazes are not as harmful as hexane. I used ehexane because I could not find heptane in my area.
Thanks for commenting :D
In Canada, there is Bestine (rubber dissolver) I used it for colored pencil. It is 100% heptane.
it could be used but its boiling point is higher 98,42 degr C instead of 69 C in case of distilling it; but if that is not a disadvantage then why not ?
Totally agree! The only disavantage is that it requieres more heat but as you say....
Other people could say it may degrade the oil but using steam distillation is basically boiling water which is close to 100C so.....
Totally agree! Some people may say the compounds could degrade but we are applying temperatures that are close to 100C so I dont think this could happen...
How to turn essential oil to crystals?
Well that depends hardly on the essential oil used. It is known that menthol crystals came out of solution after cooling mint essential oil, but that does not happen very often and many times the product is not pure and requiers further purification :D
I f that what it takes to make your own essntial oil it is much better to buy it you practically be a chemist
But you can save yourself money and time and buy lab equipment and distill over and over again. Plus if you have a significant other, bonding over chemistry is always a nice way to improve the chemistry between the two of you (no pun(s) intended)
afte watch this video, i decided to buy instead of making it
Hi! It is always cheaper to buy instead of making it. Not only for essential oils. But it is fun to perform and also you get your own. Watch my latest video, maybe with that quantity you change your mind ;D
Nation Of Our Hobbies I think you are right, unless I had a extremely large harvest of rosemary or lavender, etc, it is much cheaper to buy the essential oil bottle than making it to fill a few drops in a tiny bottle. Still, it's very interesting video! I enjoyed it very much!
This can be done by anyone who want to wish? Secondly yr text is very light. And fast forwarded very fast. My eyes are not sharp. I couldnt read.
Yu speak by ur mouth while making. And give text also.but consistancy must be there. Whole process video without missing single action.
Instead of text on screen, why don’t you speak and tell us what your doing?
Because it is much more time consuming and difficult, but yes, I am planning for giving my own voice in future videos. I am from Spain so not an english native speaker ;D
