摘　　要：目的:建立生、煅石膏粉晶XRD鉴定分析方法。方法:应用粉晶XRD分析方法,对石膏、煅石膏等进行粉晶XRD指纹图谱分析及特征标记峰鉴别。结果:对16种生石膏样品、5种煅石膏样品含石膏制剂清咽六味散进行粉晶XRD分析鉴定,获得了石膏、煅石膏粉晶XRD指纹图谱及特征标记峰值。结论:生、煅石膏具有完全不同粉晶XRD指纹图谱,粉晶XRD法可用于石膏、煅石膏以及含石膏的中药成方散剂的鉴定。Objective： To establish the analysis method for gypsum and calcined gypsum by XRPD. Method：XRPD fingerprints and strong lines of gypsum and calcined gypsum were analyzed. Result： Sixteen specimens of gypsum, 5 specimens of calcined gypsum and gypsum contained preparation Qingyanliuweisan were analyzed and identified by XRPD. XRD strong lines of gypsum and calcined gypsum were acquired. Conclusion： The method established can be used for identification of gypsum and calcined gypsum because of different XRPD fingerprints.
