[Dissolution and differentiation of phytochemical components from mixture of Radix Paeoiae Alba and Radix Glycyrrhizae with different ratios].
OBJECTIVE
To investigate dissolution properties among different components with various polarities and to distinguish these groups from each other.


METHODS
Ultraviolet fingerprint spectra (UV FPS) of the components from Baishao (Radix Paeoiae Alba) and Gancao (Radix Glycyrrhizae) with various proportions, extracted with chloroform, ethanol and water successively, were obtained. The analysis was performed on the absolute and relative absorptions of peaks in UV FPS.


RESULTS
Dissolutions in different rates and in synergy among chemical components were observed, by which different components can be distinguished.


CONCLUSIONS
Dissolution kinetics and processes of the various chemical components from medicinal herbs are of great difference.
