淫羊藿为常用中药,具有补肾助阳作用。为了探讨其免疫药理作用,本研究工作首先提取分离和鉴定了共有效成分—多糖和黄酮类。 1、淫羊藿多糖:淫羊藿水煎液经不同浓度乙醇提取与沉淀、水溶、脱脂、反复3—4次水溶醇沉、脱水干燥后得到淫羊藿多糖。 Epimedium is a commonly used traditional Chinese medicine that has kidney-boosting and yang-boosting effects. In order to explore its immunopharmacological effects, this work first extracted, isolated and identified the co-active ingredients—polysaccharides and flavonoids. 1. Epimedium Polysaccharides: Epimedium decoction is extracted and precipitated with ethanol at different concentrations, dissolved in water, delipidated, and repeatedly decomposed and dried for 3 to 4 times to obtain epimedium polysaccharide.
