title: Composite constituent: lactucenyl acetate, a novel migrated lupane triterpenoid from Lactuca indica revision of structure of tarolupenyl acetate.
abstract: Lactucenyl acetate (1), a new member of migrated lupane triterpenoids was isolated from Lactuca indica and its structure was elucidated on the basis of spectral analyses. The structure of tarolupenyl acetate was revised as lup-19(21)-en-3β-yl acetate (2).
