From the exudate of Salvia
wagneriana Polak, beside the known ursolic acid, two pentaoxygenated
triterpenoids were isolated. Their structures were determined as
3-oxo-11alpha,19beta,20,22beta-tetrahydroxy-lupane (1) and
3beta,11alpha,19beta,20,22beta-pentahydroxy-lupane (2) using a
combination of one- and two-dimensional NMR techniques.
