为探索高ECG(epicatechin gallate)型儿茶素产品的工艺制备途径,以大叶种复合儿茶素为材料,过AB-8树脂上吸附的儿茶素经乙醇解吸后,配套采用溶剂萃取后续工序,可同时制得ECG含量高达67.22%的儿茶素专化产品与含量为88.13%的咖啡因产品.

With large leaf variety catechins selected as raw material, the catechins adsorpted by the AB8 resin chromatography is eluted with 95% of ethanol.Followed by some necessary processes such as organic solvent extraction, a special kind of catechins product with 67.22% of ECG and 88.13% of caffeine product is prepared,which presents a new effective...
