| 摘 要： | 采用超声波提取（UE）和微波萃取（ME）两种前处理方法提取普洱茶的挥发性成分,利用气相色谱-质谱（GC-MS）联用仪进行定性检测,并加入乙酸苯乙酯作为内标进行定量分析。结果表明：两种萃取方法共鉴定出挥发性成分88种,其中超声波萃取检测出79种,微波萃取检测出69种。普洱茶的主要挥发性成分有11,14,17-二十三碳烯酸甲酯、咖啡因、棕榈酸、维生素E、β-香树脂醇、植醇等。超声波萃取法得到的提取率较高,而微波提取法耗时较短,两者各有所长,应根据需要来选择。 |

| Abstract: | Volatile components in Pu-er tea were extracted with ultrasonic wave extraction(UE) and microwave extraction(ME),identified by chromatography/mass spectrometry(GC-MS) and quantified by internal standard method with 2-phenylethyl acetate as an internal standard solvent.The results showed that eighty-eight compounds from Pu-er tea were identified,including seventy-nine by UE and sixty-nine by ME.The main constituents were 11,14,17-Eicosatrienoic acid,methyl ester,coffeine,palmitinic acid,vitamin E,beta-amyrin... |
