同时蒸馏萃取箬竹叶挥发油的气相色谱-质谱分析

采用同时蒸馏萃取装置提取箬竹叶的挥发性成分，然后经气相色谱- 质谱联用技术对挥发性成分进行分离鉴定。分离出了86 种成分，鉴定了其中64 种，占箬竹叶挥发油总峰面积的83.86%。其中主要成分为棕榈酸(18.57%)、茴香脑(11.16%)、植酮(7.15%)、油酸(3.31%)、植醇(3.06%)、α- 紫罗兰酮(3.04%)、对乙烯基愈木酚(2.51%)、2- 羟基肉桂酸(2.51%)、正壬醛(1.22%)、2,6,6- 三甲基-3- 环己烯-1- 乙醇(1.20%)、5,6,7,7a- 四氢化-4,4,7a- 三甲基-2(4H)苯并呋喃酮(1.17%)、4-(2,6,6- 三甲基- 三甲基-2- 环己烯基)-2- 丁酮(1.16%)、1- 甲氧基-4-(2- 丙烯基)- 苯(1.11%)、十八醛(1.08%)、叶醛(0.94%)、异植物醇(0.89%)、酞酸双-(2- 乙基己基)- 酯(0.87%)、苯乙醛(0.79%)、蒎烷(0.79%)、雪松醇(0.72%)。

GC-MS Analysis of Volatile Oil Extracted from Indocalamus latifolius Leaves by Simultaneous Distillation and Extraction

The volatile components were extracted from leaves of Indocalamus latifolius by simultaneous distillation and extraction, and analyzed by gas chromatography-mass spectrum (GC-MS). From total 86 components, 64 components were identified, which accounted for 83.86% of the total peak area of the volatile oil. Among them, the major componnets were hexadecanoic acid (18.57%), anethole (11.16%), 6,10,14-trimethyl-2-pentadecanone (7.15%), oleic acid (3.31%), phytol (3.06%), ionone (3.04%), 2-methoxy-4-vinylphenol (2.51%),3-(2-hydroxyphenyl)-2-propenoic acid (2.51%), nonanal (1.22%), 2,6,6-trimethyl-1-cyclohexene-1-ethanol (1.20%), 5,6,7,7a,-tetrahydro-4,4,7a-trimethyl-2(4H)-benzofuranone (1.17%), 4-(2, 6,6-trimethyl-2-cyclohexen-1-yl)-2-butanone (1.16%), 1-methoxy-4-(2-propenyl)-benzene (1.11%), octadecanal (1.08%), (E)- 2-hexenal (0.94%), isophytol (0.89%), bis(2-ethylhexyl)phthalate (0.87%), benzene acetaldehyde (0.79%), pinane (0.79%), and cedrol (0.72%).
