The identifiable characteristics of Angelica sinensis radix, A. pubescens radix and Levisticum officinale radix were studied by ultraviolet absorption spectrum. The UV absorption spectra of A. sinensis radix, A. pubescens radix and L. officinale radix in different polar solvents were compared by ultraviolet absorption spectra lines group (UASLG) method. There are obvious differences between A. sinensis radix and A. pubescens radix in four polar solvents, while A. sinensis radix and L. officinale radix can only be identified in anhydrous ethanol and distilled water solvents. The UASLG method can be used to identify A. sinensis radix and its confusions such as A. pubescens radix and L. officinale radix.
