Description

Rumphioside C belongs to the class of organic compounds known as diterpene glycosides. These are diterpenoids in which an isoprene unit is glycosylated. methyl (2s,4ar,6r,6ar,10as,10bs)-2-(3,4-dihydroxy-2,5-dimethoxyoxolan-3-yl)-6a,10b-dimethyl-4-oxo-6-{[(2r,3r,4s,5s,6r)-3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy}-1h,2h,4ah,5h,6h,9h,10h,10ah-naphtho[2,1-c]pyran-7-carboxylate is found in Tinospora crispa. Based on a literature review very few articles have been published on Rumphioside C.
