Research Progress in Extraction and Purification of Stilbene Glucoside from Polygoni Multiflori Radix

二苯乙烯苷为何首乌的主要活性成分,具有抗衰老、神经保护、降血脂、保护肝脏、抗肿瘤等药理作用,而提取与纯化技术是其获得的关键。本文综述了近年来二苯乙烯苷的提取与纯化技术,主要包括水煎煮法、渗漉法、回流法等提取方法,以及色谱法、重结晶法、萃取法等纯化方法,并探讨其发展前景,为进一步研究及应用提供参考。

Stilbene glucoside is one of major active constitutions in Polygoni Multiflori Radix. Stilbene glucoside contributed markedly to resisting caducity, protecting nerve, reducing serum lipids, and protecting liver and antitumor activity. The extraction and purification technology is the key issue to obtain stilbene glucoside. Through research, extraction and purification technology has made a certain progress. The stilbene glycoside could be extracted by water boiling, diacolation, and backflow; then it could be purified by the method of chromatography, recrystallization, and extraction. In this article, the technologies in extracting and purifying stilbene glucoside were reviewed, and the prospect of stilbene glucoside preparation was discussed to lay the foundation for further research and application.
