Abstract Two 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.
