摘要
One new triterpenoid olean-18-ene-1 beta, 2 alpha, 3 beta-triol (1) along with four known compounds were isolated from the chloroform extract of the aerial part of Salvia atropatana Bunge. The known compounds were two flavonoids, 5-hydroxy-7,4'-dimethoxyflavone (2) and 5-hydroxy-6,7,4'-trimethoxyflavone (3), an abietane-type diterpene namely taxodione (4) and a phytosterol namely gamma-sitosterol (5). The structure of (1) was elucidated by comprehensive spectroscopic analysis including electron ionization-mass spectra (EI-MS), H-1 NMR, C-13 NMR, distortionless enhancement by polarization transfer (DEPT), H, H correlation spectroscopy (COSY), heteronuclear multiple quantum coherence (HMQC) and heteronuclear multiple bond correlation (HMBC). The structure of known compounds 2-5 were identified by comparison of their spectral data with those reported in the literature.
