摘要
目的对深绿山龙眼Helicianilagirica种子的化学成分进行研究。方法采用乙醇提取,石油醚、二氯甲烷、正丁醇萃取,硅胶柱色谱分离,通过理化性质和光谱分析鉴定结构。结果从石油醚部分分离鉴定4个化合物:正十六烷酸(Ⅰ)、β-谷甾醇(Ⅱ)、β-谷甾醇-3-O-β-D-吡喃葡萄糖-6′-乙酸酯(Ⅲ)、胡萝卜苷(Ⅳ)。结论以上化合物均为首次从该种植物中分离得到,其中化合物Ⅰ、Ⅲ、Ⅳ为首次从山龙眼属植物中得到,化合物Ⅲ为新的天然产物。
Objective To study the chemical constituents of Helicia nilagirica. Methods The ethanol extract was seperated by petroleum ether, dichloromethane, and n-butanol in sequence, then isolated by silica gel column chromatography. The structures were identified and elucidated by physicochemical pro-(perties) and spectral analysis. Results Four compounds were isolated from the petroleum ether extract and identified as n-hexadecane acid (Ⅰ), β-sitosterol (Ⅱ), β-sitosterol-3-O-β-D-glucoside-6′-acetate (Ⅲ), and daucosterol (Ⅳ). Conclusion All the compounds are isolated from the plant for the first time. Compounds Ⅰ, Ⅲ, Ⅳ are isolated from the plants of Helicia Lour. for the first time, and compound Ⅲ is a new natural product.
