Resveratrol-derived stilbenoids and biological activity evaluation of seed extracts of Cenchrus echinatus L.

A phytochemical study of the ethyl acetate fractions from the partition of seeds and roots methanol extracts of Cenchrus echinatus L. led to the isolation of three resveratrol-derived stilbenoids: pallidol (1), carasiphenol C (2) and nepalensinol B (3).
