朱砂生品和炮制品X-射线衍射Fourier指纹图谱比较研究

X-ray diffraction Fourier fingerprint of Cinnabar

采用粉末XRD技术对11批朱砂生品、炮制品的XRD Fourier指纹图谱的共有模式进行了测定,并在此基础上进行了模糊聚类分析和相似度评价.结果显示,生品有17个共有峰,炮制品有15个共有峰; 11批朱砂样品可聚为两类,生品相似度均在0. 93以上,炮制品的相似度均在0. 95以上;生品指纹图谱1、2、4、6号峰均为Hg S的特征峰.

The common pattern of XRD Fourier fingerprint of 11 batches of raw and processed cinnabar products were determined by powder XRD technique,and fuzzy cluster analysis and similarity evaluation were further carried out.The results showed that there were 17 and 15 common peaks in raw products and processed products,respectively.Eleven cinnabar samples could be divided into two groups.The similarity of raw products and processed products were above 0.93and 0.95,respectively.The fingerprint peaks 1,2,4 and 6of raw products were all characteristic peaks of HgS.
