成果介绍

本发明提供了一种植物缩合单宁高聚体的提取方法，包括下述步骤：将清洗干净的植物样品冷冻干燥处理后粉碎研磨，然后加入70％丙酮水溶液，超声提取、离心及旋转蒸发处理后，再将提取的单宁粗提液萃取去脂，剩余水相部分去除有机溶剂后再冷冻干燥处理, 得到的单宁粗提物溶于水后置于第一色谱柱，依次采用蒸馏水、60％甲醇溶液、100％甲醇溶液和70％丙酮溶液冲洗，收集70％丙酮的洗脱液置于第二色谱柱，采用三种不同比例组成的丙酮、甲醇和水的混合液洗脱三次，分别收集各次洗脱液，即得到不同聚合度峰值的缩合单宁高聚体。本发明可有效提纯植物体中高聚合度的缩合单宁，为目前大分子植物多酚的结构与活性研究领域提供了新的途径。
