摘要
∶以溶剂萃取法从白柠檬果皮提取精油，并用硅胶柱将精油分成碳氢化合物和含氧化合物两大部分． 利用气相色谱和质谱联用系统测定了白柠檬果皮油的香气成分，并依据各成分的保留指数，鉴定出７５种挥发性成分． 其中有２３种碳氢化合物、１２种醇类物质、１７种醛类物质、１１种酯类物质、２种酚类物质、２种醚类物质和８种酮类物质．
Based on laboratorial experiments, the essential oil of lime was extracted from the peel by solution extraction, and separated into fractions of hydrocarbon and oxygenated compound through a silicagel column. Both fractions were analyzed by combined capollary gas chromatography mass spectrometry(GC MS). 75 volatile components including 23 hydrocarbons, 12 alcohols, 17 aldehydes, 11 esters, 2 phenols, 2 ethers, and 8 ketones, were identified by GC MS and Retention Indices.
