Research on Dammarane Saponins of Panax notoginseng (Burk.) F. H. Chen(II)

We employed repeated column chromatography for macroporous resin,silicgel and ODS and obtained five compounds from 70% EtOH extracts of Panax notoginseng-ginsenoside Rg3(7),ginsenoside Rd(8),notoginsenoside K(9),ginsenoside Rb1(10) and ginsenoside Rb3(11).We also identify their structures with spectroscopic analysis and chemical evidence.
