ABSTRACT
<p><b>OBJECTIVE</b>To develop an HPLC method for fingerprint determination of the astragalosides injection.</p><p><b>METHOD</b>Analyses were carried out at 25 degrees C on a Zorbax SB-C18 column (4.6 mm x 250 mm,5 microm). Mobile phase A was water, and B was acetonitrile. The analysis followed a linear gradient program. Initial conditions were 15% B; 0 to approximately 65 min, changed to 60% B. The flow rate was 0.8 mL x min(-1). The drift tube temparature of the ELSD was 105 degrees C, and gas flowrate was 2.7 L x min(-1).</p><p><b>RESULT</b>The RSD of relative retention time of the common peaks in the plant material, the extract and the injection fingerprints was less than 0.1%, and there was good similarity among 10 batches of samples.</p><p><b>CONCLUSION</b>The method was reliable and simple which could be used for quality control of the injection.</p>
