中文摘要: 研究青钱柳石油醚提取物的化学成分。青钱柳叶用石油醚冷浸提取,浓缩旋干后用正己烷溶解,通过气相色谱-质谱(gas chromatography-mass spectrometry,GC-MS)联用法测定其化学成分,质谱图与标准谱库进行比对分析,确定各化合物,并用峰面积归一化法计算各类物质的相对含量。结果表明,青钱柳石油醚部位化学成分主要由脂肪类、芳香类、类芳香、生物碱、甾体、萜类化合物组成,其中棕榈酸、叶绿醇、亚麻酸、1-十九烯、β-谷甾醇5种物质的含量相对较多,分别为17.15%、10.23%、27.24%、9.21%、12.11%。研究表明,青钱柳叶作为茶叶饮用对人体有很好的保健作用,特别是在治疗“三高症”方面有显著的效果。
Abstract:To study the chemical constituents of petroleum ether extract from cyclocarya paliurus.Petroleum ether soaking method is used to extract cyclocarya paliurus leaves.The extract was concentrated and dried,and then dissolved in hexane.The chemical composition was determined by gas chromatography mass spectrometry(GC-MS),then compare and analyze of mass spectra and standard spectral library,and calculate the relative content of various substances by peak area normalization method.The result indicates that the chemical constituents of the petroleum ether fraction of cyclocarya paliurus are mainly composed of aliphatic compounds,aromatic compounds,quasi aromatic compounds,alkaloids,steroids,terpenoids.The contents of the 5 substances including n-Hexadecanoic acid,Phytol,(Z,Z,Z)-9,12,15-Octadecatrienoic acid,1-Nonadecene,beta-Sitosterol are relatively more,respectively,17.15%,10.23%,27.24%,9.21%,12.11%.The research shows that cyclocarya paliurus leaves as tea has a very good health care function,especially in the treatment of“three high disease”.
