摘要
采用水蒸气蒸馏法提取不同季节紫丁香叶挥发性化学成分,用气相色谱法分离,质谱法鉴定其结构,对不同季节紫丁香叶挥发性化学成分变化进行研究。结果表明,紫丁香叶挥发油成分和含量在不同季节有很大的变化,5月份紫丁香叶的挥发油中主要成分为萜类化合物,而6、7月份紫丁香叶的挥发油中主要成分为青叶醇、α-绿叶烯和香叶芳樟醇。
Variation of the volatile components from leaf of Syringa Oblata Lindl. at different season was described. The volatile substances from leaves of Syringa Oblata Lindl. were extracted by hydro-distillation. The components were separated by gas chromatography and identified by gas chromatography-mass spectrometry （GC/MS）. The results show that the yield and composition of the volatile oil at different season are notably varied. The major compounds Of the volatile oil from leaves of Syringa Oblata Lindl. are terpene constituents in May. The major compounds of the volatile oil from leaves of Syringa Oblata Lindl. are 3-hexen-l-ol, α-patcholene and geranyllinalool in June and July.
