Study on applying principle component analysis to data processing on chromatographic fingerprints for Pinellia Cum Bile / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To explore the utility of principle component analysis (PCA) on chromatographic data for quality control to Dannanxing (Pinellia Cum Bile).</p><p><b>METHOD</b>Chromatographic fingerprints of sample were determined by TLC, PCA and multivariat analysis were used for data processing.</p><p><b>RESULT</b>The quantitative differences among samples procesed with different biles and heating time were found with the method.</p><p><b>CONCLUSION</b>PCA could be used in data processing for chromato-gramphic fingerprints of Dannanxing.</p>
