摘　　要：目的:分析比较山绿茶茎和叶中挥发油成分。方法:采用水蒸气蒸馏法分别提取山绿茶茎和叶的挥发油,通过气相色谱-质谱联用法对这2个部位挥发油成分进行对比研究,并用面积归一化法获得各化合物的相对含量。结果:从山绿茶茎中鉴定出24个成分,占挥发油总量的94.97%;从叶中鉴定出33个成分,占挥发油总量的98.48%。茎与叶挥发油成分中均含有的化合物有:糠醛、2,4-已二烯、(Z)-2,6-二甲基-2,6-辛二烯、乙酸己酯、双戊烯、正辛醇、顺-α,α-5-三甲基-5-乙烯基四氢化呋喃-2-甲醇、萜品油烯、芳樟醇、α-松油醇、β-环柠檬醛、橙花醇、香叶醇、己酸环己酯、β-紫罗兰酮。结论:该方法结果准确,为山绿茶的质量标准制定及进一步开发利用该药材提供了科学依据。Objective： To analyze the chemical components of the essential oil from different parts of the Ilex hainanensis and provide scientific basis for its quality control. Method： The volatile oil from the leaves, stem of I. hainanensis was obtained by steam distillation and analyzed by gas chromatography-mass spectrometry. The relative content was determined by area normalization. Result： Twenty-four components were identified from the stem, in which accounting for 94.97% of total volatile oil. 33 components were identified from the leaves, in which accounting for 98.48% of total volatile oil. Stems and leaves contain volatile oil composition of compounds： furfural, （2E, 4E） -hexadiene, （6Z） -2, 6-dimethyl-2, 6-oetadiene, hexylacetate, dipentene, 1-octhnol, 5- ethenyltetrahydro-, alpha, alpha-5-trimethyl-, cis-2-furanmethanol, terpinolen, inalool, alpha-terpineol, betacyclocitral, （Z） -geraniol, geraniol, cyclohexyl n-hexanoate, irisone. Conclusion： The results can be used as the quality standard and provide scientific basis for further development and utilization of I. hainanensis.
