二次柱层析制备高纯度表没食子儿茶素没食子酸酯(EGCG)的工艺研究
Study on preparation process of high purity of epigallocatechin gallate(EGOG) by column chromatography
摘要
Abstract
A method is described for purification of epigallocatechin gallate (EGCG) by employing polyamide/silica gel column chromatography. The raw material was commercial tea polyphenols. The operating conditions of the chromatographic steps were investigated, first preliminary separation of EGCG by employing polyamide column chromatography, and then preparation of high purity of EGCG by employing silica gel column chromatography. The purification of EGCG is over 98% by using relative low level tea polyphenols (70% TP) for raw materials in this process.关键词
