海南草珊瑚石油醚部位化学成分研究

目的:研究海南草珊瑚全草的化学成分.方法:采用各种柱色谱分离,通过波谱进行结构鉴定.结果:从海南草珊瑚全草石油醚部位中分离得到了9个化合物,分别鉴定为棕榈酸(1),花生酸(2),β-谷甾醇(3),硬脂酸(4),大黄素(5),大黄酚(6),2',3'-二羟基4',6'-二甲氧基查耳酮(7),2'-羟基4',6'-二甲氧基查耳酮(8),cardamonin(9).结论:化合物1～9均是首次从该植物中分离得到,化合物2,5～9为首次从该科中分离得到.

Chemical study on petroleum ether portion of Sarcandra hainanensis

Objective: To study the chemical constituents in the whole plants of Sarcandra hainanensis.  Method: The chemical constituents were isolated by various column chromatographic methods. The structures were identified by spectral data.  Result: Nine compounds, palmitic acid (1), icosanoic acid (2), β-sitosterol (3), octadecanoic (4), acidchrysophanol (5), emodin (6), 2′, 3′-dihydroxy-4′, 6′-dimethoxychalcone (7), 2′-hydroxy-4′, 6′-dimethoxychalcone (8), cardamonin (9) were isolated and identified.  Conclusion: Compounds 1-9 were obtained from this plant for the first time. Compounds 2, 5-9 were isolated from family Chloranthaceae for the first time.
