EGCG3" Me提取与分离工艺研究
Study on Extraction and Separation Process of EGCG3"Me
摘要
Abstract
The extraction and separation process of EGCG3"Me was studied by HPLC, polyamide resin and HPTLC methods. According to the orthogonal experimental design, the optimum extracting conditions of EGCG3"Me were as follows: alcohol concentration 70%, reflux time 30 min, reflux temperature 80℃ and solid-liquid ratio 1:10. And the yield of EGCG3"Me was 0.89%. Large amount of EGCG3"Me was found in the elution of alcohol concentration 40% and 60%. With elution of methanol: chloroform (7:2), the high purity EGCG3"Me was obtained by further separation and purification of 100~120 mesh polyamide resin.关键词
