Three new phenolic glycosides and a new triterpenoid from the stems of Scolopia chinensis.
Three new phenolic glycosides, scolochinenosides C-E ( 1- 3), and a new triterpenoid, scolopianate A ( 4), were isolated from the stems of SCOLOPIA CHINENSIS, along with 15 known compounds. The structures of the new compounds were elucidated by means of extensive spectroscopic and chemical methods. Compound 3 contains a novel highly oxygenated lactone bridge ring attached at the aglycone. Six lanostane triterpenoids ( 10- 15) were discovered for the first time in a species other than GANODERMA LUCIDUM (Polyporaceae). In addition, the phenolic glycosides were evaluated for their inhibitory activity against snake venom phosphodiesterase I.
