摘　　要：为制备富含γ-氨基丁酸（GABA）藤茶（Ampelopsis grossedentata）,采用二氧化碳（CO2）厌氧处理野生藤茶和人工栽培藤茶鲜叶,经杀青、烘干和粉碎后,利用丙酮和AlCl3去除色素,分光光度法测定藤茶中GABA的含量。结果表明：未厌氧处理时,藤茶中GABA含量为0.874 91.270 7mg/g;而CO2厌氧处理4h,野生藤茶和人工藤茶中GABA含量均达最高值,分别为1.751 8mg/g和2.509 3mg/g;CO2厌氧处理4h能显著提高野生藤茶和人工藤茶GABA的含量。The GABA content in wild and home planted A.grossedentata flesh leaves treated with CO2,was determined by spectrophotometry after fixation,drying,smash and pigment removal processing technology to produce A.grossedentata with high GABA content.Results：The GABA content in untreated wild and home planted A.grossedentataflesh leaves is 0.874 91.270 7mg/g but the GABA content in wild and home planted A.grossedentataflesh leaves treated with CO2 for 4hreaches 1.751 8 mg/g and2.509 3mg/g respectively,which indicates CO2 treatment for 4hcan improve GABA content in wild and home planted Ampelosis grossedentata significantly.
