为了分析莲雾叶精油的化学组成和开发利用莲雾叶提供科学参考，本文采用超临界CO2萃取技术提取莲雾叶中的精油，运用气相色谱-质谱（GC-MS）联用技术对其化学成分进行分离和鉴定，并用峰面积归一化法确定各组分的相对含量。结果表明：从莲雾叶精油中分离出79个色谱峰，鉴定出36个化合物，占总离子峰相对含量的86.72%。其主要由烯、醇、酚、酸、酯、烯烃氧化物及杂环化合物组成，主要化学成分有β-石竹烯（14.32%），δ-杜松烯（11.78%），Tau-杜松醇（8.85%），γ-杜松烯（5.87%），α-杜松醇（5.27%），石竹烯氧化物（5.12%），表姜烯（2.88%），库贝醇（1.69%），α-芹子烯（1.49%）等。

To analyse the chemical composition of essential oil of syzygium samarangense leaf and provide the scientific proof for exploitation of syzygium samarangense leaf , its essential oil was extracted by supercritical CO2 fluid extraction technology in this paper. Their compositions and relative contents were quantitatively determined by GC-MS with peak area normalization method. Results showed that seventy-nine chromatogram peaks from essential oil of syzygium samarangense leaf were isolated , thirty-six volatile compounds had been identified, which was accounted for 86.72 % of total volatile compounds, which contained compounds of alkenes,alcohols, phenols, acids, esters, alkylene oxide and heterocyclic compound. The predominant volatile components wereβ-caryophyllene (14.32%),δ-Cadinene (11.78%),γ-Cadinene (5.87%),α-cadinol (5.27%), caryophyllene oxide (5.12%), epizonaren (2.88%), cubenol (1.69%) andα--selinene (1.49%).
