泰山紫草和新疆紫草挥发油成分的GC-MS分析

目的:分析比较泰山紫草与新疆紫草干燥根的挥发油成分。方法:用水蒸气蒸馏法提取泰山紫草与新疆紫草干燥根挥发油,用气相色谱-质谱(GC-MS)联用法进行分析测定。结果:从泰山紫草与新疆紫草干燥根挥发油中分别鉴定出34种和36种成分,占挥发油色谱总峰面积的70.16%和74.79%,其中共有组分为4种。泰山紫草挥发油中相对质量分数较高的组分为2,6-二叔丁基对甲酚(9.29%)、2,4-二叔丁基-1,3戊二烯(8.17%)和反式橙花叔醇(6.05%);新疆紫草中相对质量分数较高的组分为诱虫烯(16.28%)、3-烯丙基-2-甲氧基苯酚(6.20%)与樟脑(5.82%)。结论:本试验可为紫草的进一步开发和利用提供科学根据。

Analysis of the Volatile Oil from Lithospermum erythrorhizon and Arnebia euchroma by GC-MS

OBJECTIVE：To analyze the volatile oil extracted from the root of Lithospermum erythrorhizon and Arnebia euchroma.METHODS：Volatile oil were extracted from L.erythrorhizon and A.euchroma by steam distillation and determined by GC-MS.RESULTS：34 components and 36 components of volatile oil extracted from the root of L.erythrorhizon and A.euchroma were separated and identified respectively,accounting for 70.16% and 74.79% of the total peak area.There were 4 kinds of common peak among these components.The main components were 2,6-di-tert-butyl-p-Cresol（9.29%）,2,4-di-t-butyl-1,3-Pentadiene（8.17%）,and trans-Nerolidol（6.05%） in L.erythrorhizon and muscalure（16.28%）,3-Allyl-2-methoxyphenol（6.20%）and camphor（5.82%） in A.euchroma.CONCLUSION：The study can provide scientific basis for the further development of Radix Arnebiae.
