Experiment of extracting Salviae miltiorrhizae on using O/W microemulsion / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the feasibility of extracting the fat-soluble and the water-solubility substances from Salviae Miltiorrhizae with O/W Microemulsion.</p><p><b>METHOD</b>With the yield of Tanshinone IIA and Salvianolic acid B as index, compere with efficiency of extracting Salviae Miltiorrhizae by suing the different media (water, alcohol and microemulsion), using different extraction methods (heat, microwave, ultrasonic), using different formulations of O/W microemulsion.</p><p><b>RESULT</b>The extracting yield of Tanshinone IIA and Salvianolic acid B are more than 70% by using microemulsion at mean time. It is good of the abilities of extraction of liposolubility compounds such as the Tanshinone IIA by the microemulsion. The formulations of microemulsion have remarkable effect for extracting Salviae Miltiorrhizae.</p><p><b>CONCLUSION</b>It is feasibiale that extracted Salviae Miltiorrhizae by using O/W microemulsion as a solvents.</p>
