【摘要】 目的研究雷公藤的化学成分及其细胞毒活性。方法用硅胶柱色谱、凝胶柱色谱分离,制备高效液相色谱纯化,得到单体化合物,用各种有机波谱鉴定化合物结构;以MTT法测试各化合物的抗癌活性。结果分离得到5个萜类化合物,鉴定为雷酚萜L(3-epi-triptobenzeneB,Ⅰ)、雷酚萜B(3β,14-dihydroxy-abieta-8,11,13-triene,triptobenzeneB,Ⅱ)、雷酚萜E(wilforolE,Ⅲ)、雷酚萜酸(triptohairicacid,Ⅳ)、雷酚萜酸甲醚[11-hydroxy-14-methoxy-18(4→3)-abeo-abietan-3,8,11,13-tetraen-18-oic-acid,hypoglicacid,Ⅴ]。结论化合物Ⅰ为新化合物,命名为雷酚萜L(triptobenzeneL),化合物Ⅳ为首次分离得到。细胞毒实验表明各化合物均有一定的抗癌活性。更多还原

【Abstract】 Objective To study the anti-cancer constituents from Tripterygium wilfordii. Methods Chemical constituents were isolated by repeated column chromatography (silica gel, Toyopearl HW-40 C and preparative HPLC), their structures were elucidated on the basis of spectroscopic methods, and the anti-cancer activity was screened by MTT method. Results Five diterpenes, 3-epi-triptobenzene B (Ⅰ), 3β, 14-dihydroxy-abieta-8, 11, 13-triene (triptobenzene B,Ⅱ), wilforol E (Ⅲ), triptohairic acid (Ⅳ), and 11-hydroxy-14-methoxy-18(4→3)-abeo-abietan-3, 8, 11, 13-tetraen-18-oic-acid (hypoglic acid, Ⅴ) were isolated from T. wilfordii. Conclusion Compound Ⅰ is a new compound named as triptobenzene L, compound Ⅳ is isolated for the first time. The compounds Ⅰ-Ⅴ show the positive anti-cancer effects on HeLa and L929 cell lines.更多还原
