    Abstract:
    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.
