[Comparisons between NIR and HPLC fingerprint on quality stability of Shudihuang decoction pieces].
OBJECTIVE
To establish a new method for evaluating quality stability of Shudihuang decoction pieces with near-infrared spectrum.


METHODS
Clustering analysis was used to distinguish different Shudihuang samples. And comparisons between NIR and HPLC fringerprint.


RESULTS
Results of clustering reflected the similar degree among these samples. Compared with HPLC fingerprint, NIR analytical process fast and convenient with exact results.


CONCLUSIONS
NIR is a feasible and effective approach to examine the quality stability of Shudihuang decoction pieces with unique virtues.
