| 摘要: | From the methanolic extract of the leaves of Planchonella duclitan, 2 alpha, 3 alpha, 19 alpha, 23-tetrahydroxy-13,27cyclours-11-en-28-oic acid (1), myrianthic acid (2), 2-hydroxyursolic acid (3), ursolic acid (4), pomolic acid (5), rotundic acid (6), andjacournaric acid (7) were isolated, and their structures were elucidated on the basis of their spectroscopic analysis. Among them, compound 1 was a new cyclopropyl ursane-type triterpenc acid. Additionally, Compounds 4 and 7 showed significant cytotoxicity toward human colorectal carcinoma cell line HT29 and human breast carcinoma cell line MCF-7 with IC50 values ranging from 5.8 +/- 1.4 to 6.5 +/- 1.9 mu M. |
