Rhapontin

Rhapontin is a natural stilbenoid glycoside first isolated from rhubarb rhizomes. It is converted by glucosidases to rhapontigenin (Cay-13293), a resveratrol analog with antioxidant and anti-cancer activity. Rhapontigenin derived enzymatically from rhapontin has also been found to have antibiotic activity as well as inhibit melanin synthesis.Formal Name: 3-hydroxy-5-[(1E)-2-(3-hydroxy-4-methoxyphenyl)ethenyl]phenyl-beta-D-glucopyranoside.
