气相色谱/质谱法分析紫藤荚挥发油化学成分

摘要

With the purpose of developing and using wisteria pods,its chemical componen!s of volatile oil is analysed. The volatile oil in wisteria pods was extracted by steam distillation. The components of volatile oil was separated and structurally identified by gas chromatography/mass spectrometry, the relative contents of the components with the peak-area normalization method in gas chromatography. 14 compounds have been identified from the volatile oil of wisteria pods, accounting 87.49% of total volatile oil. The principal constituents of the volatile oil is 3-methyl-oxiran-2-yl-methanol,Others are the acetic ether, acetic acid,benzoic aldehyde,etc.There exist great differences in constutients of volatile oil in pods and flwours of wisteria%研究了紫藤荚挥发油的化学成分,为其开发利用奠定基础。用水蒸汽蒸馏法从紫藤荚中提取挥发油,用气相色谱-质谱联用分析法进行成分分析,用色谱峰面积归一化法测定各组分相对含量。结果表明,共鉴定出14种化学成分,占挥发油总量的87.49%,其主要成分为2,3-环氧基-1-丁醇,其它依次是乙酸乙酯、乙酸、苯甲醛等,与文献报道紫藤花挥发油成分差别较大。
