Abstract: 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.
Key words: stilbene glucoside; extraction; purification
何首乌为蓼科植物何首乌Polygonum multiflorum Thunb.的干燥块根,主要以生品或制何首乌入药。生首乌具有润肠、解毒功效,制何首乌则具有补肝肾、益精血、乌须发功效。何首乌的化学成分主要为蒽醌类化合物、二苯乙烯苷类化合物、磷脂类化合物等。其中二苯乙烯苷因具有多种生物活性及药理作用,已成为临床研究热点,其含量也成为何首乌药材的专属性指标。随着二苯乙烯苷临床研究的深入,其提取与纯化技术也成为该领域的研究重点。目前,二苯乙烯苷的提取与纯化方法工艺复杂、效率较低,难以实现产业化。因此,研究开发高效的提取与纯化工艺对二苯乙烯苷稳定性、药理活性及临床应用等研究的开展具有重要意义。本文综述近年来二苯乙烯苷的提取与纯化技术研究进展,以期为其开发及应用提供参考。
