英文摘要 | This paper describes the chemical investigation of the less polar constituents present in the leaves of Drypetes hieranensis. This study led to the characterization of nine compounds from the CHCl□-soluble fraction via repeated column chromatography. They are squalene (1), methyl putranjivate (2), β-sitosterol (3), stigmasterol (4), 3-oxo-friedelan-29-ol (5), hexamethylcoruleoellagic acid (6), 3β,29-dihydroxy-friedelane (7), 3-O-β-glucosyl-β-sitosterol (8), and 3-0-β-glucosyl-stigmasterol (9). Among these, compounds 1,5-7 were Isolated for the first time from the species of Drypetes genus. The and □C NMR assignments of compounds 2, 5 and 7 were made by elaborated spectral analysis. |
