Abstract
OBJECTIVE: To study the chemical constituents from the root of Actinidia chinensis. METHOD: The roots of A. chinensis were extracted with 95% EtOH. The EtOH extract was suspended in H2O and extracted with petroleum ether, EtOAc and BuOH successively. The compounds were isolated with column chromatography from the EtOAc fraction, and elucidated on the basis of spectral analysis(MS, IR, 1H-NMR, 13C-NMR). RESULT: Seven compounds were isolated from the root of A. chinensis, and the structures were identified as 2alpha-hydroxyoleanolic acid (1), 2alpha-hydroxyursolic acid (2), euscaphic acid (3), 23-hydroxyursolic acid (4), 3beta-O-acetylursolic acid (5), ergosta4, 6, 8, (14), 22-tetraen-3-one (6), beta-steriol (7). CONCLUSION: All the compounds were obtained from the root of A. chinensis for the first time.
