目的:通过比较不同加工方法制得的北沙参中粗多糖(Polysaccharide of Radix Glehnia,GLP)对阴虚小鼠的免疫调节作用,探讨北沙参去皮和不去皮的意义。方法:采用去皮和不去皮2种方法加工北沙参,分别提取去皮北沙参中的粗多糖(GLP1)和未去...目的:通过比较不同加工方法制得的北沙参中粗多糖(Polysaccharide of Radix Glehnia,GLP)对阴虚小鼠的免疫调节作用,探讨北沙参去皮和不去皮的意义。方法:采用去皮和不去皮2种方法加工北沙参,分别提取去皮北沙参中的粗多糖(GLP1)和未去皮北沙参中的粗多糖(GLP2);制备阴虚小鼠模型,观察小鼠体质量变化,检测其脾脏抗体生成细胞(AFC)、迟发型超敏反应(DTH)和腹腔巨噬细胞(MΦ)吞噬百分率、吞噬指数等免疫指标。结果:GLP1和GLP2均可使阴虚小鼠体质量显著增加(P<0.05或P<0.01);亦能显著促进阴虚小鼠脾脏AFC的生成(P<0.05或P<0.01);增强DTH反应(P<0.01);对腹腔MΦ的吞噬百分率和吞噬指数无明显影响(P>0.05);且2种北沙参粗多糖(GLP1、GLP2)各相同剂量组之间的作用无显著性差异(P>0.05)。结论:2种北沙参粗多糖GLP1和GLP2在增强机体免疫功能方面无显著性差异,说明北沙参可以不去皮应用,为改进北沙参的传统加工方法提供了实验依据。展开更多
北沙参为常用中药,2005版《中华人民共和国药典》收载为伞形科植物珊瑚菜Glehnia littoralisFr,Schmidt ex Miq.的干燥根。该植物主要分布于山东、辽宁、河北、浙江、江苏、广东、福建、台湾等地,生于海边、沙滩或为栽培;夏秋两季...北沙参为常用中药,2005版《中华人民共和国药典》收载为伞形科植物珊瑚菜Glehnia littoralisFr,Schmidt ex Miq.的干燥根。该植物主要分布于山东、辽宁、河北、浙江、江苏、广东、福建、台湾等地,生于海边、沙滩或为栽培;夏秋两季采挖,除去须根,洗净,稍晾,置沸水中烫后除去外皮,或洗净直接干燥。本品味甘微苦,性微寒,归肺、胃经。有养阴清肺、益胃生津之功效,主要用于肺热,燥咳,劳嗽痰血,热病津伤口渴。现就北沙参的化学成分及药理研究进展综述如下。展开更多
