[Comparative study of dissolved matter of glycyrrhizic acid before and after supermicro-pulverization of Radix Glycyrrhizae].
OBJECTIVE
To investigate various activities of dissolved matter of glycyrrhizic acid of Radix Glycyrrhizae and the powder by supermicro-pulverization.


METHODS
The contents of glycyrrhizic acid in different samples were tested.


RESULTS
The dissolved matter of glycyrrhizic acid was greatly increased by supermicro-pulverization. The more time used for grinding, the smaller the size of the powder, and the easier the glycyrrhizic acid would be dissolved.


CONCLUSIONS
Supermicro-pulverization is helpful to the dissolved matter of glycyrrhizic acid of Radix Glycyrrhizae, and the size of powder exerts great influence on dissolved matter of glycyrrhizic acid.
