顶空萃取-气相色谱-质谱法测定一种儿童专用防痱止痒水的挥发性成分

Analysis of Volatile Flavor Components in One Type of Remove Philippine and Itching Water by Headspace Extraction-GC/MS

采用顶空萃取-气相色谱/质谱法分析鉴定防痱止痒水的挥发性成分。结果表明:共检测出35种挥发性成分,主要成分为乙醇和酞酸二乙酯,其它成分主要包括醇、烯、酯、甘菊环等。检出的物质中,α-蒎烯、β-蒎烯、莰烯、桉叶醇、樟脑、α-萜品醇、龙脑、醋酸异龙脑酯、石竹烯为野菊花挥发油的有效成分;苯甲酸甲酯、苯甲酸苄酯、丁香酚为金银花挥发油的有效成分;广藿香醇为广藿香提取物的主要成分。α-蒎烯、β-月桂烯、β-蒎烯、莰烯、薄荷醇、丁香酚等成分都具有较强的驱避蚊虫的作用。

The volatile components in one type of remove philippine and itching water were analyzed by headspace extraction-gas chromatography-mass spectrometry（HS-GC/MS）.The results showed that HS-GC/MS is effective in the analysis of remove philippine and itching water.35 components are separated and identified.The main components are ethyl alcohol and diethyl phthalate acid,the others are alcohols,terpenes,esters and azulenes.alpha.-Pinene,beta.-pinene,camphene,eucalyptol,camphor,p-menth-1-en-8-ol,borneol,isobornyl acetate,caryophyllene are the effective components of the volatile oil in chrysanthemum indicum L.Benzoic acid methyl ester,benzyl benzoate,eugenol are the effective components of the volatile oil in flos lonicerae.Patchouli alcohol is the effective components of the volatile oil in pogostemon cablin（blanco） benth.alpha.-Pinene,beta.-myrcene,beta.-pinene,camphene,menthol,eugenol are all effictive repellent.
