淫羊藿为常用补肾壮阳中药,但生药来源混杂。本工作对全国大多数省区所用的淫羊藿生药进行了调查和鉴定,认为市售商品主要来源于小蘖科淫羊藿属(Epimedium)8种植物。为了合理利用药物资源,特对此8种15个地区生药的质量从薄板层析、总黄酮成分含量及以抗心律不齐作用等方面进行了比较。同时对不同种淫羊藿的鉴别进行了研究,结果表明不同种淫羊藿所含化学成分相似,但在含量上和药理作用方面有差异。因此在应用时必须注意鉴别。本研究工作表明以非腺毛形态特征可有效地鉴别不同种生药。
Epimedium is a commonly used Bushen impotence medicine, but the source of crude drugs mixed. This work has investigated and identified the epimedium crude drug used in most provinces and regions in the country, and it is believed that the commercial products are mainly derived from 8 species of Epimedium. In order to make rational use of drug resources, the quality of the crude drugs used in the eightteen species in 15 areas was compared from thin-layer chromatography, total flavonoid content, and anti-arrhythmic effects. At the same time, the identification of different species of epimedium was studied. The results showed that different species of Epimedium contain similar chemical components, but there are differences in the content and pharmacological effects. Therefore, we must pay attention to the identification in the application. This study shows that non-glandular morphological characteristics can effectively identify different species of crude drugs.
