摘　　要：目的 建立补骨脂与盐（炙）补骨脂配方颗粒的红外光谱快速鉴别方法.方法 采用红外光谱结合二阶导数光谱分析补骨脂与盐补骨脂配方颗粒红外光谱特征.结果 补骨脂与盐补骨脂配方颗粒的红外光谱基本相似,仅在1 614、1 340、1 070、1 030、832、669 cm-1附近吸收峰的强度、形状略有差异;二阶导数光谱在1 800～400 cm-1区域内,谱峰强度、形状和位置变化较明显.结论 通过比较两者的红外光谱图及二阶导数光谱图,可以快速、准确地鉴别补骨脂与盐补骨脂配方颗粒.AIM To establish a rapid FTIR method for identifying Formula Granules of Psoraleae Fructus and Salted P. Fructus. METHODS Formula Granules of P. Fructus and Salted P. Fructus were researched by in- frared and second derivative spectra. RESULTS The infrared spectra of two formula granules were similar while the intensity and shape of the absorption peaks were slightly different in 1 614, 1 340, 1 070, 1 030, 832, 669 cm-1. In second derivative spectra, the intensity, shape and position of the peaks were different in the range of 1 800 - 400 cm-1 CONCLUSION Formula Granules of P. Fructus and Salted P. Fructus can be identified by the infrared spectra rapidly and accurately.
