海南草珊瑚石油醚部位化学成分研究

Chemical study on petroleum ether portion of Sarcandra hainanensis

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。

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.
