5,6-Didehydroginsenosides from the Roots of Panax notoginseng
Abstract
Two minor novel dammarane-type saponins—5,6-didehydroginsenoside Rd (1) and 5,6-didehydroginsenoside Rb1 (2)—were isolated from the dried roots of Panax notoginseng along with sixteen known saponins. The structures of the new compounds were elucidated on the basis of spectroscopic and chemical methods.
