362472-82-0 25Q6Y8Y108 Withanoside VI UNII-25Q6Y8Y108 Ergosta-5,24-dien-26-oic acid, 3-((6-o-beta-D-glucopyranosyl-beta-D-glucopyranosyl)oxy)-1,20,22-trihydroxy-, sigma-lactone, (1alpha,3beta,22R)- Withanoside VI (constituent of ashwagandha root) [DSC] Withanoside vi, (-)- (C40H62O15) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
