Comparative study of dissolved matter of glycyrrhizic acid before and after supermicro-pulverization of Radix Glycyrrhizae / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate various activities of dissolved matter of glycyrrhizic acid of Radix Glycyrrhizae and the powder by supermicro-pulverization.</p><p><b>METHOD</b>The contents of glycyrrhizic acid in different samples were tested.</p><p><b>RESULT</b>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.</p><p><b>CONCLUSION</b>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.</p>
