[目的]为普洱茶产品质量标准的制定提供依据.[方法]采用水蒸气回流法提取普洱茶中的挥发油,并对其进行气相色谱-质谱分析,采用面积归一化法对各组分进行定量.[结果]从普洱荼挥发油中共鉴定出50种化合物,其主要成分为n-棕榈酸,其次为(Z,Z)-9,12-十八碳二烯酸、顺式芳樟醇、植醇、十四烷、1,2.3-三甲氧基苯、1,2-二甲氧基苯、己醛、二十一烷和苯甲醛,以上成分占挥发油相对含量的91.43%.[结论]普洱茶挥发油中主要含醇类、酸类、醛类、烃类、酯类、杂氧类、芳香族、杂环类等7类化合物.%[ Objective ] The purpose of the research was to supply basis for formulating product quality standard for Pu' er tea. [ Method ] The volatile oil was extracted from Pu' er tea by vapor reflux method and analyzed by GC-MS,and then its components were analyzed quantitatively by area normalization method. [ Result] There were 50 kinds of compounds identified from volatile oil in Pu' er tea,its major component was nhexadecanoic acid, its secondary components were ( Z, Z ) -9,12 -octadecadienoic acid, cis-linalcol, phytol, tetradecane, 1,2,3-trimethoxy ben zene, 1,2-dimethoxy benzene ,hexanal, heneicosane and benzaldehyde and the above components accounted for 91.43％ in relative content of volatile oil in Pu' er tea. [ Conclusion ] The volatile oil in Pu' er tea mainly contained 7 kinds of compounds, such as alcohols, acids, aldehydes,hydrocarbon, esters, hetero-oxy compounds, aromatic series and heterocyclic compounds.
