黄连木果柄挥发油化学成分GC-MS分析

Determination of chemical composition of the essential oil from the fruit stalk of Pistacia chinensis Bunge by GC-MS

在已分析黄连木果实挥发油化学成分的基础上,对黄连木果柄挥发油化学成分进行GC-MS分析,以对二者挥发油成分进行比较。采用水蒸汽蒸馏法从黄连木果柄中提取挥发油,利用GC-MS联用仪对黄连木果柄挥发油的化学成分进行分析,共分离到50个组分,鉴定了其中的37个,占挥发油总量的91.917%。黄连木果柄挥发油主要成分是[1S-(1,α7,α8 aβ)]-1,2,3,5,6,7,8,8 a-八氢-1,4-二甲基-7-(甲基乙烯基)-薁(11.979%),3-蒈烯(10.640%),β-水芹烯(9.504%),1-乙烯基-1-甲基-2,4-二(1-甲基乙烯基)-环己烯(7.760%),β-蒎烯(6.227%),α-蒎烯(6.065%),D-柠檬烯(5.070%)等。黄连木果实和果柄挥发油的主要化学成分组成和含量有差异,但主要成分差别不大。

Based on the determination of chemical composition of essential oil from the fruit of Pistaeia ehinensis Bunge by GC-MS , this study analysed that of fruit stalk of P. ehinensis for comparing the differentia between the both. The essential oil was extracted from the fruit stalk of P. ehinensis by steam distillation, and then an analysis was conducted by applying GC-MS. The result shows that 50 ingredients have been found, and 37 of them have been identified, accounting for 91. 917% of the total essential oil. The main chemical components of the fruit stalk of P. ehinensis are： Azulene, 1, 2,3,5,6,7,8,8a-octahydro-1,4-dimethyl-7-（1-methylethenyl）-, [ 1S-（ 1. alpha. ,7. alpha. ,8a. beta. ） ]-（ 11. 979% ）, 3-Carene（ 10. 640% ） ,. beta. -Phellandrene （9. 504% ）, Cyclohexane, 1-ethenyl-1-methyl-2,4- his （ 1-methylethenyl ）- （7. 760% ） ,. beta. -Pinene（ 6. 227% ） ,. alpha. -Pinene （6.065%）, D-Limonene（5. 070% ）etc.. The conclusion showed the main chemical composition and aontent had differentia between essential oil of fruit and fruit stalk of P. chinensis, but the main chemical composition occured in each other essential oil.
