新鲜橄榄叶挥发油成分的气相色谱-质谱联用分析

目的分析新鲜橄榄叶挥发油成分。方法采用水蒸气蒸馏法提取新鲜橄榄叶的挥发油,经气相色谱-质谱联用(GC-MS)仪分析,归一化法测得各组分的相对含量。结果鉴定了新鲜橄榄叶挥发油化合物中的47个成分,约占相对总含量的99.7%。结论新鲜橄榄叶挥发油主要化学成分及其相对含量为反式-3-己烯-1-醇(36.58%)、异香橙烯(16.26%)、β-石竹烯(6.51%)、己醛(5.66%)、异己醇(4.92%)、2-乙氧基丙烷(4.78%)、顺式-2-戊烯-1-醇(3.10%)、顺式-3-己烯乙酸酯(2.89%)、水杨酸甲酯(2.32%)、β-荜澄茄烯(1.79%)、甘香烯(1.35%)等。

Analysis of Essential Oil from the Fresh Canariumalbum Raeusch Leaves by Gas Chromatography-Mass Spectrometry

Objective To analyze the constituents of the essential oil from fresh Canarium album Raeusch leaves.Methods Essential oil from the fresh Canarium album Raeusch leaves was extracted by steam distillation and were analyzed by gas chromatography-mass spectrometry (GC/MS). Results Forty-six compounds were identified, which accounted for over 99.7% of the essential oil. Conclusion The main components of essential oil include trans-3-hexenol(36.58%),Alloaromadendren (16.26%), .beta.-caryophyllene(6.51%),hexanal(5.66%), isohexanol(4.92%),2-ethoxypropane(4.78%),cis-2-peneten-1-ol(3.10%),cis-3-hexenyl acetate(2.89%),methyl salicylate (2.32%) and etc.
