Studies on the constituents of dwarf ginseng

Phytochemical study of the leaves of Panax trifolius L. resulted in the isolation of two flavonoids and four ginsenosides. The two flavonoids were found to be kaempferol-3,7-dirhamnoside and kaempferol-3-gluco-7-rhamnoside. The four ginsenosides were identified as ginsenoside —Rd, —Rc, —Rb3 and notoginsenoside-Fe. The common aglycones of these flavonoids and ginsenosides were shown to be kaempferol and (20S)-protopanaxadiol, respectively.
