GC-MS法检测白花败酱草与黄花败酱草挥发性成分

Determination of volatile component from Patrinia villosa(Thunb.) Juss. and Patrinia scabiosaefolia Fisch by GC- MS

利用气相色谱-质谱联用(GC-MS)分析白花败酱草与黄花败酱草中挥发性成分.采用水蒸气蒸馏法提取败酱草中挥发性成分,利用气质联用技术对成分进行分析并应用NIST 05a.L标准质谱图库检索鉴定各成分、采用面积归一化法计算各成分的相对百分含量.结果表明:黄花败酱草挥发油中鉴定54个成分,占总量的94.56%.白花败酱草挥发油中共鉴定36种成分,占总量的89.87%.两种挥发油共同含有成分9种,分别为hexanal,2-Pentylfuran,benzeneacetaldehyde,α-Ionene,1,2,3,4-Tetrahydro-1,6,8-trimthylnaphthalene,1,2,3,4-Tetrahydro-1,5,7-trimethylnaphthalene,β-Damascenone,hexahydrofarnesylacetone,palmitic acid.首次对白花败酱草与黄花败酱草挥发性成分进行对比分析,为白花败酱草与黄花败酱草的鉴别、质量评价以及挥发性成分开发利用提供基础.

To analyze the chemical constituents in the essential oil of Patrinia villosa（ Thunb.） Juss and Patrinia scabiosaefolia Fisch. The essential oil obtained by the hydrodistillation of the leaves of Patrinia scabiosaefolia Fisch and Patrinia villosa（ Thunb.） Juss.were analyzed by a combination of capillary GC / MS analytic techniques. Results indicated that 54 components comprising 94. 56% of essential oil in leaves of P. scabiosaefolia Fisch and 36 components comprising 89. 87% of oil in leaves of P. Villosa Juss. were identified,respectively. 9 common constituents,hexanal,2- Pentylfuran,benzeneacetaldehyde,α-Ionene,1,2,3,4- Tetrahydro- 1,6,8- trimthylnaphthalene,1,2,3,4- Tetrahydro- 1,5,7- trimethylnaphthalene,β- Damascenone,Hexahydrofarnesylacetone and palmitic acid,were identified in two species of Baijiangcao. This was the first report to make a comparison of essential oil constituents in two species of Bai Jiang Cao,which could have identification between the two leaves on essential oil ingredient,and even could give a support for quality control.
