摘要
采用乙酸乙酯对茶多酚原料进行预处理,使EGCG得到富集。为模拟移动床分离EGCG作准备。萃取的条件是:萃取剂的配比为V水:V乙酸乙酯=1:3,萃取液的pH值为4,固液比为1:12,萃取次数为2次。
The raw material was pretreated with EtoAc . The EGCG was enriched.The technology preparated for simulated moving bed chromatography separation epigallocatechin gallate .The extraction conditions: the mixture rate water and EtoAc is V_水 :V_乙_酸_乙_酯=1:3, the pH value is 4,the ratio of raw material and solution is 1:12,the extraction is twice.
