Megastigmane and flavone glycosides from Strophioblachia fimbricalyx Boerl.

Three megastigmane glucosides, bridelionoside B, ampelopsisionoside and 3-hydroxy-5,6-epoxy-beta-ionol 9-O-beta-D-glucopyranoside, together with three flavone glycosides, apigenin 7-O-beta-D-glucopyranoside, isovitexin and spinosin, were isolated from the aerial portions of Strophioblachia fimbricalyx. The structure determinations were based on physical data and spectroscopic evidence.
