Hi sir, There is a confusion in Aloe Emodin and Rhein structures at (1:50) & (10:56) Can you please explain it?

[@egpat]

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.

Sir sennidin A dextro also called trans, is correct or wrong?

[@egpat]

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.

@@egpat thank you sir for clearing daily my doubts 👍

Sir disintegration time for film coated tablet is 30 or 60 min ? Pls reply Sir

[@egpat]

For film coated 30 min and sugar coated it is 60 min.

[@praveenkumar-jd1zl]

Thank you Sir 👍

[@prashantdubey5044]

Sir, Sennidin A there should be 10R,10R ,bcoz its 10th position of anthracene

[@egpat]

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.
