ABSTRACT
<p><b>OBJECTIVE</b>To compare the stability of baicalin and baicalein in buffered aqueous solutions and mouse plasma in order to discuss the degradation mechanism and the method of disposing samples.</p><p><b>METHOD</b>HPLC-ECD was used to determine baicalin and baicalein in different conditions, and the disposing samples methods were selected to stabilize them.</p><p><b>RESULT</b>Baicalin and baicalein in the buffered aqueous solution at pH 7.4 was more stable than that in the mouse plasma. After adding Vit C in the buffered aqueous solution, the stability of baicalin and baicalein could be improved obviously and their remained percents were 102% and 100%. The stability of baicalin and baicalein could be enhanced distinctly in the mouse plasma only when adding Vit C and 1 mol x L(-1) HCl, and furthermore their remained percentage was up to 98% and 103%.</p><p><b>CONCLUSION</b>The stability of baicalin and baicalein is related to the oxidation and enzyme degradation and it can be improved by adding Vit C and 1 mol x L(-1) HCl in the solution.</p>
