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-tetrahydroxylupane (1) and 3beta, 11alpha, 19beta,20,22beta-pentahydroxy-lupane (2) using a combination of one- and two-dimensional NMR techniques

Abstract
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-tetrahydroxylupane (1) and 3beta, 11alpha, 19beta,20,22beta-pentahydroxy-lupane (2) using a combination of one- and two-dimensional NMR techniques
