新疆拟百里香挥发油的气相色谱-质谱分析

Analysis of Volatile Oils of Thymus Proximus Serg. from Xinjiang by Gas Chromatography-Mass Spectrometry

摘要: 利用水蒸气蒸馏法提取了新疆拟百里香挥发油，测得含量为0.16%。采用气相色谱-质谱联用技术对拟百里香的挥发性成分进行分离鉴定，分离出73种成分，共确认了其中的69种成分。用峰面积归一化法确定了各成分的相对含量，其中主要成分为百里香酚(27.99%)、p-聚伞花素(25.42%)、γ-松油烯(17.95%)、β-甜没药烯(3.87%)、香芹酚(2.5%)、4-蒈烯(2.39%)、长叶薄荷酮(1.99%)、内冰片(1.68%)、β-月桂烯(1.35%)、石竹烯(1.09%)和α-崖柏烯(1.01%)。

Abstract: The volatile oil was extracted from Thymus Proximus Serg. by water distillation method．The content of volatile oil is 0.16％．The chemical components of volatile oil were separated and identified by gas chromatography-mass spectrometry (GC／MS). 69 compounds are identified from 73 constituents．The relative content of components were determined with peak area normalization method. The major constituents of volatile oil are thymol (27.99%), p-cymene(25.42%), γ-terpinene (17.95%), β-bisabolene(3.87%), carvacrol (2.5%), 4-carene(2.39%), pulegone(1.99%), endo-borneol(1.68%), β-myrcene(1.35%), caryophyllene (1.09%) and α-thujene(1.01%)。
