新疆维吾尔医用药材新疆茜草挥发油的GC-MS分析

Analysis of volatile oil from Rubia tinctorum L.cultured in Xinjiang by GC-MS

目的:研究维吾尔医用药材新疆茜草挥发油化学成份及相对含量。方法:利用水蒸气蒸馏法提取新疆茜草挥发油成分,运用气相色谱-质谱联用技术,结合计算机质谱图库检索技术对分离的化合物进行结构分析。结果:共鉴定了30个成分,占挥发性物质含量的86.32%。应用峰面积归一法确定各成分的相对含量。结论:新疆茜草挥发油的化学成分主要有:茶螺烷(17.37%)、糠醛(11.10%)、苯乙醛(6.01%)、丁香酚(5.47%)、芷香酮(3.87%)等。

AIM： To study the chemical components and contents of the volatile oil from the Rubia tinctorum L.. METHODS： The volatile oil was extracted by steam distillation-extract method, the chemical constituents of the volatile oil from the herb were identified by gas chromatography-mass spectrometry （GC-MS）. RESULTS： Thirty compounds were identified, which accounted for over 86.32% of the volatile oil. CONCLUSION ： The major components were theaspirane （ 17.37% ）, 2-furaldehyde（ 11.10% ）, benzeneacetaldehyde（6.01% ）, eugenol （5.47%） , ionone（3.87% ） , and so on.
