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.
