一种附子甘草多糖提取物及其制备方法
本专利技术涉及一种附子甘草多糖提取物及其制备方法,属于医药领域。
技术介绍
附子来源于毛莨科乌头属植物乌头(AconitumcarmichaeliDebx.)的子根及加工品,具有回阳救逆、补火助阳、祛风寒湿邪之功,用于亡阳虚脱、肢冷脉微、阳萎、宫冷、心腹冷痛、虚寒吐泻、阴寒水肿。甘草为豆科植物甘草(GlycyrrhizauralensisFisch)、光果甘草(G.glabraL.)或胀果甘草(G.inflataBatalin)的根及根茎,具有补心气、益脾气、祛痰止咳平喘、缓急止痛、清热解毒、调和药性之功,多用于气虚诸证及减毒。中医临床上,常用附子、甘草、干姜等组成回阳救逆剂,主治阳气衰弱等证。而对于仅将附子和甘草配伍使用的研究,目前主要集中在两者配伍的减毒作用方面,鲜有涉及相关产品的利用和开发。CN103272012A公开了一种附子甘草提取物,由附子、甘草加水合煮,煎煮液离心、所得的沉积物干燥所得;药效实验证明其具有抗心衰的功效。然而,该提取物以乌头碱、新乌头碱、次乌头碱等毒性物质为指标性成分,在用药的安全性方面存在较大问题, ...
