Two New Dammarane Glycosides from the Acid Hydrolysis Product of Panax Notoginseng

Kunming Institute of Botany, Chinese Academy of Sciences, Kunming 650204

Received Date: 25 July 2000

Two new dammarane glycosides named notoginsenoside T₁ and T₂ were isolated from the mild acid hydrolysis products of the root saponins of Panax notoginseng. On the basis of spectroscopic evidences, their structures were elucidated to be 6-O-β-D-glucopyranosyl-24(25)-epoxy-3β,6α,12β,23 ζ-tetrahydroxydammar-20(22)(E)-ene 1 and 6-O-β-D-glucopyranosyl-24(25)-epoxy-23 ζ-methoxyl-3β,6α,12β-trihydroxydamm-ar-20(22)(E)-ene 2, respectively.
