Research on X-ray diffraction fingerprints of crude and processed pyritum / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To establish the X-ray diffraction fingerprints of crude and processed pyritum.</p><p><b>METHOD</b>X-ray diffraction fingerprint was used to analyze the crude and processed pyritum of different habitat and batch.</p><p><b>RESULT</b>The crude pyritum has 19 common peaks, while the processed ones has 11.</p><p><b>CONCLUSION</b>The X-ray diffraction can express characteristic of the crude and processed pyritum, which is specificity, accuracy and reliability and can be used for the quality control of crude and processed pyritum.</p>
