title: [Identification of Epimedium Koreanum Nakai by Fourier transfer infrared spectroscopy].
abstract: The herbal plant Epimedium Koreanum Nakai is a native herb growing in the Changbai Mountain region, Jilin province of China, and is used as a tonic, anti-rheumatic and aphrodisiac in traditional Chinese medicine. The analytical method existing for the identification of Epimedium Koreanum Nakai is time-consuming, and can not be used for fast, in situ and nondestructive analysis. Fourier transform infrared spectroscopy was used to identify wilding and planting Epimedium Koreanum Nakai. The spectra of 18 samples were analyzed. They show some differences in the intensity and the shape of absorption peaks in the range of 1,800-1,200 cm(-1). The absorption intensity of the spectra changed regularly with the producing area. So FTIR spectra could be used for the identification of Epimedium koreanum Nakai.
