ABSTRACT

<p><b>OBJECTIVE</b>To establish the quantitative method of notoginsenoside R1, ginsenoside Rg1 and Rb1 in Radix Notoginseng and its preparation Xuesaitong injection by HPLC-ELSD.</p><p><b>METHOD</b>The column was packed with 5 microm Diamonsil C18 stationary phase. The mobile phase consisted of acetonitrile-water, eluted in gradient mode. The temperature of drift tube was 105 degrees C and the nebulizer nitrogen flow rate was 2.9 L x min(-1).</p><p><b>RESULT</b>The linear ranges of the three components were 0.456-2.25 microg, 1.47-7.38 microg and 1.20-6.03 microg respectively. The average recoveries of the three components in Radix Notoginseng were 97.1% (RSD 1.9%), 96.8% (RSD 2.0%), 97.0% (RSD 2.2%) respectively; in Xuesaitong Injection were 98.7% (RSD 1.9%), 98.5% (RSD 1.8%), 98.1% (RSD 1.4%) respectively.</p><p><b>CONCLUSION</b>It was proved that the method was reliable, simple, and precise, that could be used for quality control.</p>
