花梨木叶挥发油化学成分的GC-MS分析

GC-MS Analysis of Chemical Constituents of the Volatile Oil from Leaves of Ormosia henryi Prain

采用水蒸汽蒸馏法提取分离花梨木叶中的挥发油,通过GC-MS联用仪对花梨木叶挥发油的化学成分进行分析,共鉴定出39个化学成分,主要成分为环己甲酸乙烯酯(5.10%)、三十烷(3.76%)、5,6,7,7a-四氢-4,4,7a-三甲基-2(4H)-苯呋喃酮(3.44%)、二十八烷(3.08%)、十六酸(2.35%)、二十四烷(2.26%)、榄香素(2.25%)、二十烷(2.17%)。

The volatile oil was extracted from leaves of Ormosia henryi Prain by steam distillation, and its chemical composition was analyzed by GC-MS method. The result showed that 40 components were identified, and the major chemical compositions were Cyclohexanecarboxylic acid, ethenyl ester （5. 10% ）, Triacontane （3.76%）, 2 （4H） - Benzofuranone, 5,6,7,7a - tetrahydro - 4,4,7a - tr （ 3.44% ）, Octacosane （ 3.08% ）, Hexadecanoic acid （ 2. 35% ）, Tetracosane （ 2. 26% ）, Benzene, 1,2,3 - trimethoxy - 5 - （ 2 - propenyl ） （2.25%）, Eicosane（2.17% ）.
