Two new triterpene caffeates have been isolated from the root bark of Hibiscus syriacus. Their structures were established through various spectral studies as 3beta,23,28-trihydroxy-12-oleanene 23-caffeate (1) and 3beta,23,28-trihydroxy-12-oleanene 3beta-caffeate (2). Compounds 1 and 2 showed lipid
In this study, 4 new triterpenoids-3β- acetoxy-olean-11-en,28,13β-olide (1), 3β- acetoxy-11α,12α-epoxy-olean-28,13β-olide (2), 19α-epi-betulin (3), and 20, 28-epoxy-17β,19β-lupan-3β-ol (4)-and 12 known compounds, were isolated from the root bark of Hibiscus syriacus L. by using acetone extraction.
