目的:研究新疆石榴皮(Punica granatum)的化学成分。方法:采用薄层色谱、硅胶柱色谱、MCI-gel CHP20P、Sephadex LH-20凝胶柱色谱等方法进行分离纯化,使用波谱分析技术和理化常数对照等方法对得到的化合物进行结构鉴定。结果:分离得到了10个化合物,分别为:没食子酸(1)、没食子甲酯(2)、鞣花酸(3)、(+)-儿茶素(4)、异槲皮苷(5)、D-甘露醇(6)、熊果酸(7)、齐墩果酸(8)、β-谷甾醇(9)、胡萝卜苷(10)。结论:化合物1~10均为首次从该植物中分离得到。
Objective: To study the chemical composition of Punica granatum in Xinjiang. Methods: The compounds were separated and purified by thin-layer chromatography, silica gel column chromatography, MCI-gel CHP20P and Sephadex LH-20 gel column chromatography. The structures of the obtained compounds were identified by spectral analysis and physical and chemical constants control. Results: Ten compounds were isolated and identified as gallic acid (1), gallic acid ester (2), ellagic acid (3), (+) - catechin , D-mannitol (6), ursolic acid (7), oleanolic acid (8), β-sitosterol (9) and daucosterol (10). Conclusion: Compounds 1 ~ 10 were isolated from this plant for the first time.
