广西桂枝桂叶挥发油化学成分分析

采用1102型气相色谱仪、RID检测器、BP×5化学结合相熔凝硅石毛细管柱(30m×0.32mm×0.25μm),色谱条件为色谱柱初温90℃终温215℃,载气流速为45ml/min,分流比为50∶1,分析了水蒸汽蒸馏法提取的肉桂枝、肉桂叶挥发油的化学组成。所得结果与标准谱图相符:共检出肉桂枝、肉桂叶挥发油22个组分,且均以反式肉桂醛为主要成分。该实验为中小桂油企业提供了成本低且快捷的分析方法。

Study on chemical component of essential oil from cinnamomumcassia presl and cinnamomumcassia petrophilum leaves in Guangxi

The chemical component of the essential oil extracted from cinnamomumcassia presl,and cinnamomumcassia petrophilum leaves by steam distillation were analyzed by gas chromatography (type 1102). Chromatographic conditions were as follows:BP×5 boned phase, fused silica capillary column (30 m×0.32 mm×0.25 μm), column temperature from 90℃ to 215℃; the flow rates of carrier gas 45 mL/min; split ratio 50:1.The results analyzed was agree with standard chromatographic graph, and twenty-two components of essential oil were determined, and trans-3- phenylpropenal was the major constituent of all the components. This paper provided a fast analysis method with low cost.
