【摘要】 目的:用气相色谱-质谱(GC-MS)法对云南产枇杷叶挥发油化学成分进行分析。方法:采用同时蒸馏萃取法从枇杷叶中提取挥发油,研究其分离分析的条件,对分离物质用GC-MS鉴定,归一法确定其相对百分含量。结果:鉴定了77个成分,占总离子流图峰面积的73.15%,其中主要成分为:十六酸(13.79%)、亚麻醇(5.45%)、(E)-橙花叔醇(10.95%)、(+)-香芹酮(2.56%)、2-己酰呋喃(2.23%)、榄香素(2.4%)、二氢猕猴桃内酯(2.37%)、醋酸法呢基酯(3.09%)、金合欢醇(1.82%)、α-红没药醇(1.93%)。结论:此方法稳定可靠,重复性好,可为进一步开发利用枇杷叶资源作参考。更多还原

【Abstract】 OBJECTIVE Essential oil in the leaves of Eriobotrya japonica(Thunb.) Lindl were analyzed by GC-MS.METHODS The essential oil was extracted by simultaneous distillation and solvent extraction(SED),the components were determined by GC-MS and the relatives mass fractions were acquired by gas chromatography-mass spectrometry.RESULTS 77 compounds were identified and determined,amounting to 73.15% of the total area of the peaks.The principal constituents and contents in the volatiles were n-Hexadecanoic acid(13.79%)、9,12,15-Octadecatrien-1-ol,(Z,Z,Z)-(5.45%)、(E)-nerolidol(10.95%)、(+)-Carvone(2.56%)、2-Hexanoylfuran(2.23%)、Elemicin(2.4%)、Dihydroactinidiolide(2.37%)、Farnesyl acetate(3.09%)、Farnesol(1.82%)、alpha.-Bisabolol(1.93%)etc.CONCLUSION It is a good method for the Analysis of Essential Oil in leaves of Eriobotrya japonica(Thunb.)Lindl,and it can be used as reference in the further researches.更多还原
