Stilbene derivatives from two species of Gnetaceae.
Five new stilbene oligomers (gnemonols A, B and C, gnemonoside E and gnetal) were isolated together with 2b-hydroxyampelopsin F and gnetin E from Gnetum gnemon and G. gnemonoides. The structures of the compounds were elucidated on the basis of spectral evidence.
A dimeric stilbene from Gnetum parvifolium
Abstract Ten constituents have been isolated from lianas of Gnetum parvifolium. Two novel dimeric stilbenes, gnetifolin C and D, a new stilbene glucoside and flavone, gnetifolin E and B have been identified along with six known compounds. Their structures were deduced on the basis of spectroscopic evidence.
