试图调查化学成分和他们大戟属植物 tibetica 的天线部分的生物活动。方法混合物被各种各样的色析法的方法,和他们的结构孤立并且净化包括 2D-NMR 通过广泛的分光镜的技术的使用被阐明,混合物的结构 5 和 6 被单个水晶的 X 光检查晶体学证实。所有孤立的混合物的 Bioactivities 被 MTT 方法在 A549 和 anti-angiogenesis 试金上评估。结果一新混合物,甲基 4-epi-shikimate-3-O-gallate (1 ) ,和 23,已知的成分(224 ) 从 E 的天线部分被孤立。tibetica。结论化合物 1 是新的,并且另外的混合物第一次从这植物被孤立。5, 7, 12, 13, 17 和 19 显示出的 anti-angiogenic 在 zebrafish 完成的人的肺癌症房间 A549 和混合物的生长上的 57, 9, 11, 17, 18 和 20 展出禁止的效果建模的混合物。
AIM: To investigate the chemical constituents and their biological activities of the aerial parts of Euphorbia tibetica. METHOD: Compounds were isolated and purified by various chromatographic methods, and their structures were elucidated through the use of extensive spectroscopic techniques including 2D-NMR, the structures of compounds 5 and 6 were confirmed by single-crystal X-ray crystallography. Bioactivities of all the isolated compounds were evaluated by the MTT method on A549 and anti-angiogenesis assay. RESULTS: One new compound, methyl 4-epi-shikimate-3-O-gallate (1), together with twenty-three known constituents (2-24) were isolated from the aerial parts ofE. tibetica. CONCLUSION: Compound 1 is new, and the other compounds were isolated from this plant for the first time. Compounds 5-7, 9, 11, 17, 18 and 20 exhibited inhibitory effects on the growth of human lung cancer cell A549 and compounds 5, 7, 12, 13, 17 and 19 showed anti-angiogenic effects in a zebrafish model.
