Lanostane-Type Triterpenoids from Scilla scilloides and Structure Revision of Drimiopsin D

摘要

AbstractTwo hitherto unknown lanostane-type triterpenoids, namely scillascillol (>1) and scillascillone (>2), and a hitherto unknown norlanostane-triterpene glycoside, namely scillascilloside B-1 (>3), were isolated from the ethanol extract of the whole plants of Scilla scilloides. Their structures were elucidated on the basis of extensive spectroscopic studies. In addition, the structure of drimiopsin D (>6a) has been revised as 2,5-dimethoxy-8-methyl-1,3,6-trihydroxyxanthone (>6) by reanalysis of the spectroscopic data.
