ABSTRACT
<p><b>OBJECTIVE</b>To explore the utility of Principal Factor Analysis (PFA) in chromatographic data for quality control.</p><p><b>METHOD</b>Chromatographic fingerprints of processed root pieces of Paeonia lactiflora were determined by HPLC, the PFA was used for data processing.</p><p><b>RESULT</b>The quantitative differences among different growing areas and different processing batches were found with the method.</p><p><b>CONCLUSION</b>The method could be used in quality control for monitoring between-batch products of traditional Chinese pharmaceutical process.</p>

<p><b>OBJECTIVE</b>To develop an HPLC method for the determination of hyodeoxycholic acid in Bile Arisaema.</p><p><b>METHOD</b>The methanol extracts were separated on a Diamonsil ODS column eluted at 35 degrees C with a mixture of methanol-water-glacial acetic acid (75:25:0.01) at flow-rate 1.0 mL x min(-1). The drift-tube temperature of ELSD was 85 degrees C, and the flow rate of air was 3.0 L x min(-1).</p><p><b>RESULT</b>Hyodeoxycholic acid in methanol extract was well separated, the relationship of logarithms of injection amount and peak area was linear (r = 0.9998) over the range of 2.4-24 microg. The average recovery was 97.1% (RSD 2.9%, n=5).</p><p><b>CONCLUSION</b>The method could be used for quality control of Bile Arisaema.</p>
