[Comparisons between NIR and HPLC fingerprint on quality stability of Shudihuang decoction pieces].

ABSTRACT

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