摘要(Abstract):

目的 :分析进口索马里乳香与埃塞俄比亚乳香挥发油的化学成分 ,并建立其相应主成分的含量测定方法。方法 :GC MS联用鉴定乳香挥发油成分 ;GC法进行含量测定 ,SE 5 4填充柱 (2 .1m× 3.2mm) ,柱温为程序升温 ,初始温度 80℃ ,保持 1min ,终止温度 170℃ ,每分钟升温 15℃。结果 :分别鉴定了索马里乳香挥发油 40种成分与埃塞俄比亚乳香挥发油 2 2种成分 ,其中索马里乳香挥发油主成分为α 蒎烯 ,埃塞俄比亚乳香挥发油主成分为乙酸辛酯 ;对 17批次不同样品进行了测定 ,α 蒎烯线性范围 0~ 10 .80 μg ,r =0 .9995 ,加样回收率为 98.16 % ,RSD 1.83% ;乙酸辛酯线性范围为 0~ 10 .32 μg ,r =0 .9996 ,加样回收率为 99.5 6 % ,RSD 1.36 %。 结论 :通过本项研究 ,为乳香进口药材质量标准的制订奠定基础。
Objective: To analyse the chemical components of the essential oil of Gum olibanum somalilnds and Gum olibanum Ethiopia , and to set up determination methods of their main components. Method: Two kinds of essential oil are identified by GC-MS, and assayed by Gas chromatography, using SE-54 as the packing material (column 2.1 m×3.2 mm), with column temperature starting from 80 ℃, holding for 1 min, and then rising at the rate of 15 ℃ per minute to 170 ℃. Result: 40 kinds of chemical compounds in the essential oil of Gum olibanum somalilnds and 22 kinds of those of Gum olibanum Ethiopia were identified by GC-MS, the main component in the essential oil of Gum olibanum somalilnds being α-pinene, and the main one of Gum olibanum Ethiopia being Octyl acetate 17 batches of samples were determined with the linear range of α-pinene being 0~ 10.80 μg, the correlation coefficient being 0.9995, the recovery being 98.16%, RSD being 1.83%; the linear range of Octyl acetate being 0~10.32 μg, the correlation coefficient being 0.9996, the recovery being 99.56%,and RSD being 1.36%. Conclusion: This study can be used for the setting up of the specification of Olibanum.
