摘要: 本实验用原子吸收法测定了恩施富硒地区野菜鸡屎藤的总含硒量(102.987μg/g)及挥发性成分中的含硒量(31.546μg/g);用水蒸汽蒸馏法提取了鸡屎藤挥发油,并用气相色谱-质谱联用仪对鸡屎藤挥发性物质的化学成分进行了分离和鉴定,分离并鉴定出33个组分,占峰面积的91.76%,并用峰面积归一化法测定了各成分的质量分数。其主要挥发性成分为:谜类、醇(烯醇)类、酮类及酯类化合物等各四种,含N化合物八种,含S化合物两种,其它为酸酐、醛、萜、烷烃、烯烃等物质。含量较高的β-丙内酯、二甲基砜、乙偶姻、安乃近、2,3-二甲基-2,4,6-环庚三烯-1-酮、3-丁烯-2-酮、4-丁二醇-丙烯酸酯、反-1,2:4,5-二环氧萜烷、N-甲磺酸咪唑。

Abstract: The total Se content and the Se content in the volatile compounds was determined respectively by the method of atomic absorption spectrometer for Paederia scandens. The volatile compounds of Paederia scandens were isolated with steam distillation,and identified by capillary GC-MS method. 33 volatile components were identified and determined, accounting for 91.76% of the total area of the peaks. The relative contents of the constituents were determined by area nomalization method. The main volatile compounds are: β-propiolactone, dimethyl sulphone, acetoin, analgin, 2,4,6-cycloheptatrien-1-one,2,3- dimethyl, 3-buten-2-one, 4-butanediol monoacrylate, trans-1,2:4,5-diepoxy-p-menthane, N-methanesulfonylimidazole.
