摘　　要：目的:研究新鲜海南产柠檬草精油的化学成分。方法:采用水蒸气蒸馏法提取柠檬草精油,运用气质谱联用(GC-MS)技术对挥发油成分进行分析,并采用峰面积归一化法确定各成分的相对百分含量。结果:共鉴定出12种成分,其中相对百分含量超过2%的有香叶醛(49.35%)、橙花醛(29.52%)、香叶醇(8.28%)、乙酸香叶酯(3.16%)、棕榈酸(2.64%)及橙花醇(2.56%)等。结论:新鲜海南柠檬草精油中主要成分为柠檬醛,百分含量高达78.87%。Objective： To investigate the chemical constituents of the essential oil extracted from CymboDogon citratus （DC.） Stapf （lemongrass） in Hainan province. Methods： The essential oil was extracted by water steam distillation and then analyzed by GC-MS. The relative percentage of each component was determined by peak area normalization method. Results： A total of 12 compounds were identified in the lemongrass oil, of which the relative percentage that was more than 2% were general（49.35%）, nerol（29.52%）,geraniol（8. 28%）,geranyl acetate（3. 16%）,palmitic acid（2. 64%）and nerol（2. 56%）. Conclusions： The main constituent of the essential oil from lemongrass in Hainan was citral, the relative percentage of which is as high as 78.87%.
