梅州4 种柚子精油GC-MS 分析

    Analysis of volatile components of the peel of four different pummelos cultivars from Meizhou by GC-MS

    • 摘要: 以广东省梅州市金柚、沙田柚、奥兰柚、蜜柚4 种柚子为原料,通过气质联用(GC-MS)技术对其果皮精油的挥发性成分进行对比分析。结果显示,4 种柚子精油中共检测出62 种挥发性成分,其中烯烃类31 种,醇类12 种,醛类7 种,烷烃类3 种,酯类4 种,酮类3 种,其他种类2 种;4 种精油成分的数量及种类存在明显差异,其中金柚精油共检测出24 种挥发性化合物,沙田柚35 种,奥兰柚38 种,蜜柚34种;4 种精油共有组分为12 种,主要成分均为D- 柠檬烯、β- 月桂烯。研究结果说明4 种柚子精油主要香气成分相似,但不同种类精油间存在特征性差异,这可为梅州柚子精油的综合开发利用提供参考。

       

      Abstract: In the present study,the volatile components of essential oils of Jin pomelo,Shatian pomelo, Aolan pomelo,and Mi pomelo from Meizhou city,Guangdong province were analyzed by gas chromatographymass spectrometry( GC-MS). The results showed that there are 62 kinds of volatile components in essential oils, and 31 kinds of alkenes taking the largest part in these components,followed by 12 kinds of alcohols,7 kinds of aldehyds,3 kinds of alkanes,4 kinds of esters,3 kinds of ketones and 2 kinds of other compounds. There were obvious differences in quantities and categories among different kinds of volatile compounds in essential oils,Jin pomelo,Shatian pomelo,Aolan pomelo,and Mi pomelo had 24,35,38 and 34 kinds of components,respectively. There were 12 components in common in the four pomelo essential oils,and the main components were D-limonene and β-Myrcene. The results indicated that although the four pummelo essential oils had similar aroma and volatile components,their qualities differed to a certain extent. These results provided a theoretical basis for further comprehensive development and utilization of pummelo essential oils in Meizhou city.
