柿Diospyros kaki L.果肉中含大量具生理活性的多酚类物质,包括缩合鞣质等。然而由于柿果肉中鞣质具大分子结构和强的可吸收性,因此对该类成分的分离、测定较为困难;并且由于品种及产地的不同,鞣质的结构也有所差异。通过大孔吸附树脂、超滤法、凝胶渗透色谱法(GPC)与HPLC-MS结
Persimmon Diospyros kaki L. Pulp contains a large number of physiologically active polyphenols, including condensed tannins and so on. However, because of the macromolecular structure and strong absorbability of tannin in persimmon pulp, it is difficult to separate and determine the components of tannin, and the structure of tannin is also different due to different varieties and origins. Through macroporous resin, ultrafiltration, gel permeation chromatography (GPC) and HPLC-MS
