RESUMEN
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), 3?, 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.
