| Abstract: | 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 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 and RADIX GLEHNIAE.Conclusion]The method was simple and accurate,and could be used to distinguish RADIX GINSENG from its counterfeits. |
