【 摘 要 】

From the leaves of Bauhinia forficata kaempferol and four flavonoid glycosides, 3,7-di-O-a-L-rhamnopyranosylkaempferol, 3,7-di-O-a-L-rhamnopyranosylquercetin, 3-O-[a-L-rhamnopyranosyl-(1®6)-b-D-glucopyranosyl]-7-O-a-L-rhamnopyranosylkaempferol and 3-O-[a-L-rhamnopyranosyl-(1®6)-b-D-glucopyranosyl]-7-O-a-L-rhamnopyranosylquercetin were obtained. From the flowers only the flavonoid 7-O-a-L-rhamnopyranosylkaempferol was isolated. The structures were established by chemical and spectroscopic methods.
