箭叶淫羊藿不同部位含量差异研究

Study on the Difference of Content in Different Parts of Epimedium sagittatum

为了解箭叶淫羊藿根、根茎、叶、叶茎、叶柄、花叶、花茎、花柄共8个部位的含量差异,本研究采用HPLC法和UV法,对含量结果进行差异分析。分析结果表明,叶、根茎、根、叶茎等部位含量较高,其中以叶的含量最高,根与根茎的朝藿定C含量总体高于地上部位。本研究证明了2020年版《中国药典》所规定淫羊藿药用部位为叶的合理性。同时分析结果发现,根茎有开发作为药用部位的潜力。

In order to understand the content difference of 8 parts of Epimedium sagittatum, including root, rhizome, leaf, leaf stem, petiole, flower leaf, flower stem and HPLC and UV spectrophotometry were used to analyze the difference of content. The results showed that the contents of Epimedin C in leaves, rhizomes, roots and leaf stems were higher, and the content of Epimedin C in leaves was the highest. The content of Epimedin C in roots and rhizomes was higher than that in aboveground parts. This study proved the rationality of the medicinal part of Epimedium as leaf in the 2020 edition of “Pharmacopoeia of the People’s Republic of China”. At the same time, the analysis results showed that rhizomes had the potential to be developed as medicinal parts.
