Establishment of X-Ray Diffraction Fingerprint for Natrii Sulfas Exsiccatus

Abstract:

Objective: To establish X-ray diffraction characteristic fingerprint of Natrii Sulfas Exsiccatus. Method: X-ray diffraction method was applied to do qualitative analysis of 10 batches of Natrii Sulfas Exsiccatus,correlation coefficients and angle cosine were applied to calculate similarity of shared peak in each sample. Result: Similarity of shared peak in X-ray diffraction of Natrii Sulfas Exsiccatus was>95%. Conclusion: This X-ray diffraction characteristic fingerprint of Natrii Sulfas Exsiccatus had strong specificity,it could provide a reference for identification and quality evaluation of Natrii Sulfas Exsiccatus.
