【摘要】 [Objective] To establish a method for distinguishing RADIX GINSENG from its counterfeits including RADIX PLATYCODI,RADIX ISATIDIS and RADIX GLEHNIAE by ultraviolet absorption spectra lines group (UASLG).[Method] The 4 kinds of medicines were respectively extracted with five different solvents of water,ethanol,petroleum ether,ethyl acetate and chloroform.Then,their absorbance in UV and one-order derivative spectra was measured.[Result] There were obvious differences regarding peak position and absorbance in ultraviolet absorption spectra among RADIX GINSENG and RADIX PLATYCODI,RADIX ISATIDIS,RADIX GLEHNIAE.[Conclusion]The method is simple and accurate,and could be used to distinguish RADIX GINSENG from its counterfeits.
