Two new dammarane-type triterpenoid saponins from notoginseng medicinal fungal substance.
Two new dammarane-type triterpenoid saponins, namely ginsenoside Rk6(1) and ginsenoside-Rh22(2), were isolated from notoginseng medicinal fungal substance. The structures of 1 and 2 were established as 3β,6α,12β,26-tetrahydroxydammar-20(21),24(25)(E)-diene-6-O-β-D-glucopyranoside and 3β,6α, 20(S)-trihydroxy-12(R),23(R)-expoxy-13(S),17(S)-dammar-24-ene-6-O-β-D-glucopyranoside on the basis of spectroscopic analysis and chemical analysis, respectively.
