红枣挥发性芳香物的气相色谱—质谱分析

    Identification of Volatile Fragrant Compounds of Chinese Dates by Gas Chromatography-Mass Spectrometry(GC-MS) Analysis

    • 摘要: 以陕西产油枣、木枣、梨枣等为原料,经处理并用气相色谱—质谱仪测定挥发性物质,共鉴定出59种化合物,其中有8种醛、酮类物质,13种酯类物质,14种有机酸,17种烷、烯类物质,5种醚及呋喃衍生物,苯甲醇和苯并噻唑。不同品种的红枣所含挥发性成分不同,4个样品中鉴定出9种相同的化合物。在有机酸中,相对含量最高的是Δ9十六烯酸,从木枣与梨枣中检出含有1-异丙基-4,7-二甲基-1,2,3,5,6,8a-六氢萘。

       

      Abstract: The identification of volatile oil from three species of Chinese dates produced in Shaanxi Province was carried out by steam distillation and the treatment of the distillation with ethyl ether to obtain oil fraction. The volatile oil was identified by GS-MS. The results showed that there were 8 aldehydes and ketones,13 esters, 14 organic acids, 17 alkanes and olefines, 5 ether and furan derivatives, benzyl alcohol and benzothiazole among the 59 identified compounds. The various compounds were separated from the three species of dates, except for the same compounds in each sample. The Δ9-hexadecenoic acid was the most significant content among the organic acids. The finding of 1-isopropyl-4,7-dimethyl-hexadien-1-y)-2-buten-1-one from the volatile oil of dates was reported first.
