摘要

Eight darmarane-type saponins,named as sanchirhinoside D(1),3β,6 α-20(S)-6,20-bis(β-D-glucopyranosyloxy)-3-hydroxy dammar-24-en-12-one(2),20(R)-ginsenoside Rg3(3),ginsenosides F2(4)and Rd(5),gypenoside XVII(6),ginsenosides Rb1(7)and ginsenoside V(8)were isolated from the 70%ethanol extract of Panax notoginseng roots by silica gel,octadecyl silane(ODS)column chromatography and HPLC,and identified by chemical and physical methods,especially by spectral analysis.Among them,1 was a new compound and 2 was a new natural product.
