Comparisons between NIR and HPLC fingerprint on quality stability of Shudihuang decoction pieces / 中国中药杂志

<p><b>OBJECTIVE</b>To establish a new method for evaluating quality stability of Shudihuang decoction pieces with near-infrared spectrum.</p><p><b>METHOD</b>Clustering analysis was used to distinguish different Shudihuang samples. And comparisons between NIR and HPLC fringerprint.</p><p><b>RESULT</b>Results of clustering reflected the similar degree among these samples. Compared with HPLC fingerprint, NIR analytical process fast and convenient with exact results.</p><p><b>CONCLUSION</b>NIR is a feasible and effective approach to examine the quality stability of Shudihuang decoction pieces with unique virtues.</p>
