[The dual-index sequence analytical method of common peak ratio and variant ratio for analysing UV fingerprint spectra of Radix Glycyrrhizae].
OBJECTIVE
To set up the dual-index sequence analytical method for UV fingerprint spectra (FPS) in which the dual indices are common peak ratio and variant ration.


METHODS
Three kinds of solvents chloroform, alcohol and water were used to extract different polarity components from Radix Glycyrrhizae, and then the UV FPS of the components were measured, which were applied to distinguish the samples.


RESULTS
This method is effective for distinguishing Radix Glycyrrhizae from inner Mongolina, Gansu and Xinjiang.


CONCLUSIONS
The UV-FPS dual-index sequence analytical method is feasible.
