摘要
通过粉末X射线衍射对藏药"佐太"、朱砂、轻粉的粉末X射线衍射(PXRD)谱图进行比对分析,明确了藏药"佐太"中汞主要以黑色的立方晶系β型HgS形式存在,建立了"佐太"粉末X射线衍射法指纹图谱。"佐太"粉晶主成分黑辰砂和硫的X射线衍射花样以强线d-(I/I0)%分别表达为:黑辰砂3.356 4/100,2.061 4/55.0,2.911 8/35.0,1.760 1/37.0,1.339 5/12.0,1.304 5/10.0,1.192 0/10.0,1.683 4/7.0,1.458 0/5.6;硫3.824 4/100,3.197 5/40.2,3.442 2/38.1,3.095 6/19.7,5.690 9/16.8,2.851 0/16.3,2.414 4/11.3。这16条衍射谱线可作为"佐太"粉末X射线衍射法指纹图谱的主要参考值,对"佐太"的快速、无损分析和"佐太"质量标准的补充具有现实意义。
A robust, direct, rapid and non-destructive X-ray diffraction crystallography method for detecting the Tibetan medicine Zuotai is presented. Powder samples of Zuotai, cinnabar and calomel were unambiguously characterized using powder X-ray diffractometry（PXRD） by comparing a practical identification of metacinnabar in the analyzed material, which confirmed the present of metacinnabar in Zuotai. At the same time, 11 strong lines in the fingerprint of Zuotai were selected to indicate the effective constituents of Zuotai, which were listed in the form of d-（I/I0）%：metacinnabar 3.356 4/100,2.061 4/55.0,2.911 8/35.0,1.760 1/37.0,1.339 5/12.0,1.304 5/10.0,1.192 0/10.0,1.683 4/7.0,1.458 0/5.6. sulfur 3.824 4/100,3.197 5/40.2,3.442 2/38.1, 3.095 6/ 19.7,5.690 9/16.8,2.851 0/16.3,2.414 4/11.3.The results showed that mercury chemical state is metacinnabar with sulfur in Tibetan medicine Zuotai. This method should be supplemented to quality control of rare traditonal Chinese medicine.
