摘　　要：朝鲜淫羊藿为常用中药,具有较高的药用和保健价值,临床用量也日益增大。但现有的分析方法操作比较烦琐,费时、费力,无法作为快速、原位、无损的检测。红外光谱法现已成为中药研究中不可缺少的工具之一。文章对18种来源于不同产地的朝鲜淫羊藿的红外光谱进行了分析、指认,利用红外光谱半定量分析方法分析了朝鲜淫羊藿的品质与原产地的关系,发现光谱随产地等因素呈现规律性的变化。初步建立了利用红外光谱简便地分析淫羊藿品质的方法。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 aphrodisiacin 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.
