中文摘要: 利用气相色谱-质谱联用(gas chromatography-mass spectrometry,GC-MS)技术分析经甲酯化的不同采收期酸枣仁的脂肪油成分组成及相对质量分数的变化。结果表明:3个时期酸枣仁的脂肪油成分总含量增加,经过GC-MS分析共检测出29种脂肪油成分,包括不饱和脂肪酸类、饱和脂肪酸类、碳氢化合物和醇类化合物这4大类组分。3个时期酸枣仁中均有其特殊的脂肪油成分,同时各时期也有相同的脂肪油成分,其中亚油酸甲酯(33.01%~34.27%)和油酸甲酯(43.66%~45.43%)为各个时期中的主要脂肪油物质。

Abstract:Using gas chromatography-mass spectrometry (GC-MS)technology to investigate the fatty oil compositions and relative mass fraction of ziziphi spinosae semen in different harvest periods after methyl esterification.The results showed that the total content of fatty oils in ziziphi spinosae semen increased in three periods.A total of 29 fatty oils were detected by GC-MS analysis,including unsaturated fatty acids,saturated fatty acids,hydrocarbons and alcohol.In three periods,the ziziphi spinosae semen had its special fatty oil component,and the same fatty oils were found in all parts.Among them,methyl linoleate(33.01%-34.27%)and methyl oleate(43.66%-45.43%)were the main volatile substances in each part.
