柱色谱分离制备低乙酸乙酯儿茶素
Column chromatography separation preparation of catechins with low content of ethyl acetate
摘要
Abstract
Catechins is a representative active substance of tea,whose preparation has been much-talked- about. Based on previous study,the thesis hoped to find the optimal control conditions to produce catechins with low content of ethyl acetate through analyzing the separation experiment condition of column chromatography. The best control condition was purifying catechins with polyamide resin and the elution sequence was 25% ethanol, ethyl acetate：80% ethanol=2：1. Product quality index for： ethyl acetate〈20mg/kg, total catechins≥ 75%, EGCG ≥ 55%, Caf〈2%, yield coefficient〉 10%.关键词
