Abstract
Three more triterpenoids were isolated from total glucosides of tripterygium wilfordii (T1). T16 and T17 were identified as salaspermic acid and as wilforlide B. T18 was a new compound. The structure of T18 was determined, as 3-oxo-22 alpha-hydroxy-delta 12-oleanen-29-oic acid by detail spectroscopic and chemical analysis, and named triptotriterpenonic acid A.
