Many of the anthraquinone glycosides including seena, cascara, rhubarb and aloe include various moieties of anthraquinones either as mono anthrones or dianthrones
Ya, Rhein is having carboxylic acid chain while Aloe-emodin has methanol side chain. So whatever described at 10:56 is correct. Earlier part was edited. Thanks for notifying this. Thanks for your interest.
Yes, since two anthrones are connected oppositely in sennidin A they are called trans but in sennidin B they are connected in similar way producing mirror image so they are considered as cis.
Sennidin A is made up of rhein which is having carboxylic acid. Therefore direction of numbering will be changed so it become 9th carbon. That's why it will have 9R,9'R configuration. Hope it is clear now. Thanks for your interest and watching video.
Sir plz upload full video of pharmacognosy.
Great 🎉

@@egpat thank you sir for clearing daily my doubts 👍
Sir, Sennidin A there should be 10R,10R ,bcoz its 10th position of anthracene
