摘　　要：为鉴别秦艽类中药材,本文应用粉末X衍射分析技术测定了8个样品的X衍射图谱,获得了秦艽类药材鉴别的特征标记峰与衍射模糊图形,结果表明各药材的衍射图不仅各具特征性,而且有较好的重现性。X衍射图谱对于性状与组织结构相似、化学成分相近的中药材的鉴别具有重要意义。To identify Radix Gentianae Macrophyllae, eight samples were analyzed by powder X-ray diffraction method. We obtained the characteristic peaks and diffraction fuzzy figures for distinguishing Radix Gentianae Macrophyllae. The results showed that every medicine had its own character which could be well repeated. X-ray diffraction figure plays an important role in distinguishing Chinese materia medica with similar shape and properties, similar tissue texture or similar chemical composition. And X - ray diffraction figure may be used as one fingerprint method for Chinese herbal medicine.
