摘要
淫羊藿是一味药用历史悠久的传统中药,具有补肾壮阳之功效。《中国药典》规定使用五种来源的淫羊藿--淫羊藿Epi mediumbrevicornu Maxim.、箭叶淫羊藿E.sagittatum(Sieb.et Zucc.)Maxi m.、柔毛淫羊藿E.pubescensMaxi m.、朝鲜淫羊藿E.koreanum Nakai和巫山淫羊藿E.wushanense T.S.Ying,但这几种药材的鉴别特征描述比较简单,传统鉴定技术很难实现这些种类和常见混淆物种的鉴别。文章采用傅里叶变换红外光谱(FTIR)及其二阶导数谱对常见淫羊藿易混淆药材--淫羊藿与朝鲜淫羊藿,柔毛淫羊藿与保靖淫羊藿E.baojingense Q.L.Chen&B.M.Yang、星花淫羊藿E.stellulatum Stearn、竹山淫羊藿E.zhushanense K.F.Wu&S.X.Qian,柔毛淫羊藿与部分天平山淫羊藿E.myrianthum Stearn,箭叶淫羊藿与粗毛淫羊藿E.acuminutum Franch.共4对易混淆药材进行鉴别研究。根据不同物种淫羊藿药材红外光谱特征的不同,基本上实现常见易混淆物种的快速鉴别。该方法有助于解决淫羊藿药材物种混乱问题。
Herba Epimedii, the dried aerial parts of Epimedium brevicornum Maxim., E.sagittatum Maxim., E.pubescens Maxim., E. wushanense T.S. Ying., and E. koreanum Nakai, has been widely used in the field of nourishing the kidney and reinforcing ‘Yang’ for centuries. The descriptions of external appearance of Herba Epimedii are rather simple, so it is difficult to identify the raw materials of Herba Epimedii only with the traditional methods. In the present paper, the methods of FTIR and the second derivative IR spectra were used for the identification of Herba Epimedii, by which, E. brevicornum Maxim. could be identified from E.koreanum Nakai,and so E.sagittatum （Sieb. et Zucc.） Maxim.from E.acuminatum Franch., as well as E.pubescens Maxim.from E.stellulatum Stearn, E.baojingensis Q.L.Chen et B.M.Yang, E.zhushanense K.F.Wu ＆ S.X.Qian and E. myrianthum Stearn. According to the features of the IR spectra of each species, a method based on FTIR for the identification of Herba Epimedii was established, and it conduced to solve the confusion of species of Herba Epimedii.
