摘要
本文采用水蒸气蒸馏萃取法提取海南暗罗叶挥发油化学成分,利用气相色谱-质谱(CC-MS)从中分离鉴定出40种化学成分,占挥发油总量的67.03％.其中主要成分为1-甲基-5-亚甲基-8-(1-甲基乙基)-1,6-二烯环十烷(18.305％),丁子香烯(6.256％)和γ-榄香烯(6.211％).所得的挥发油抑菌试验表明其对大肠杆菌和枯草芽孢杆菌表现出显著的抑制活性.
Abstract
The essential oil obtained by water-steam distillation extraction of the leaves of Polyalthia laui was analyzed by gas chromatography-mass spectrometry (GC-MS).Forty compounds were characterized accounting for 67.03％ in the oil The major components were 1-methyl-5-methylene-8-(1-methylethyl)-l,6-Cyclodecadiene(18.305％),Caryophyllene (6.256％) and γ-Elemene(6.211％).The bacteriostatic test showed that the essential oil had remarkable inhibitory effects for Escherichia coli and Bacillus subtilis.
