| 摘 要： | 为贵州黄连的进一步开发应用提供依据,采用固相微萃取-气质联用仪分析贵州黄连的挥发性成分,使用峰面积归一化法对匹配度大于80%的可检索组分进行统计分析。结果表明:贵州黄连有29个挥发性成分,即29个化合物,包括酯类、萜类、醛类和烃类。其中酯类含量最高,其次是萜类,具体分布是酯类15个(74.89%)、萜类9个(16.40%)、醛类3个(7.62%)、烃类2个(1.09%),酯类中高于1%的11个成分的总含量为72.46%,其中以月桂酸乙酯的含量最高(25.99%),其次是癸酸乙酯(12.12%)、棕榈酸乙酯(10.44%)等。贵州黄连中的酯类是现有文献中没有记载的,属首次报道;环葑烯、α-可巴烯、反式-β-金合欢烯、β-甜没药烯、顺式-α-甜没药烯、2,6-二甲基-6-(4-甲基-3-戊烯基)双环3.1.1]庚-2-烯等也是其他地方黄连中所没有,高酯类含量是贵州黄连挥发性成分的明显特点。

| Abstract: | The volatile components in C.chinensis were detected by solid-phase microextraction and gas chromatography-mass and then the detectable components with over 80％ matching rate were statistically analyzed by the peak area normalization method to provide the basis for further development and utilization of C.chinensis in Guizhou.Results:29 volatile components identified from C.chinensis belong to esters (15),terpenoids (9),aldehydes (3) and hydrocarbons (2) respectively.Total content of 11 esters components with ＞ 1％ content accounts for 72.46％ of total volatile components.The content of ethyl laurate,ethyl declate and ethyl palmitate is 25.99％,12.12％ and 10.44％ separately.The esters in C.chinensis from Guizhou is firstly reported.The volatile components of cyclofenchene,alpha-copaene,trans-beta-farnesene,beta-bisabolene,cis-alpha-bisabolene and 2,6-dimethyl-6-(4-methyl-3-pentenyl)-bicycle3.1.1]hept-2-ene are only detected in C.chinensis from Guizhou.In conclusion,the high esters content is an obvious characteristics of volatile components in C.chinensis from Guizhou. |
