Thanks alot

Thanks a lot for sharing the video. It's verw wll prepared.

❤❤

what did you make in sample, and negative control

The Good results affirmed your great work .

You don't need a standard ? Usually for antioxidant we take ascorbic acid standard... I'm new to this and kind of confused. Help me

Hello, good video, a question, where did you get the reference for the laboratory guide? HELP

Any other solvent than 99% methanol that can use???

Hlo please provide any reference link

Will you share the research article??

great video keep it up

How much pls

Thank you so much!!! This was very useful for my IBDP extended essay research !!!

I want cite this vedio, can u give link of this article where it from taken

You mentioned acid ascorbic but there isn't in video please can you tell me how you used it? and please here your control was it only dpph +methanol ?? I need the protocol

4:19- sample+methoh 5:22- each sample 1ml mixed with 3ml dpph 6:09- make up with methoh

What is the blank in the spectrometer?

Dpph a simple assay/antioxidant a big term

Amazing 👌

can someone explain for me where concentration in the result table from? thank youu

Your hand pouring technique is incredible bravo.

Thank you

Could you mention the refference to the protocol, please?

where to order this machine

Concentration ka column samja dijiye plz

Thank You very much for the video, I don't see you using ascorbic acid and you listed it in your material to use

prepararon una solución a 0,1mM no a 1M..... con eso si toman 4 mg

great

I wanted to ask something.....is 58% a good antioxidant value?

Good

Can anybody explain why his calculated IC50 value is 25 mg/ml while in the table it shows 65% Inhibition at 20 mg/ml?

Reference?? Please.

How could we determine how many mL of solvents to put into the sample?

thank you so much for your work, it is really a great help to me.

Beautiful scenery 😍

can I know why it needs ascorbic acid for this experiment?

Thank you. It's very useful🙏🏻🙏🏻❤️❤️❤️

Where is the standard solution?

DPPH 4 mg is real at that weight??

Which book you can get procedure ..name pls ...

May i know which food sample you used in your study

7:54 Calculate Inhibition% by hand i.e. ((0.301-0.284)/0.301)*100%=5.65% not 5.86%. All values of Inhibition% are incorrect.

how do you calculate the concentration?

Thanks

Sir Please provide me flowchart of dpph assay, please🙏🙏🙏🙏

Hello, how did you get 1ml, 2ml, 3ml, 4ml and 5 ml for the solution series?

what you take blank solution?

In earlier video, you write ascorbic acid in materials, but i cant see where or when you use in tutorial.
