摘　　要：目的 :研究青黛炮制原理。方法 :通过扫描电子显微镜 (SEM)和X 衍射 (XRD)方法 ,对青黛的微观结构进行了研究。结果 :经SEM发现 ,靛蓝依附于某种白色固体的表面 ,而XRD证明了吸附靛蓝的白色固体是CaCO3 。结论 :对青黛炮制原理有了新的认识 ,了解到青黛是由靛蓝等有效成分依附于CaCO3 表面而组成的。AIM: To study the processing of Indigo Naturals. METHODS: Study on the microstructure of Indigo Naturals with scanning electron microscope (SEM) and X ray diffractometer (XRD) were carried out. RESULTS: Through the SEM, it is clear that Indigo attached to the surface of some white substance, and the XRD proves that the white substance in Indigo Naturals is calcium carbonate (CaCO 3). CONCLUSION: The study about the processing of Indigo Naturals indicates that Indigo Naturals consists of Indigo and other effective compositions attached the surface of calcium carbonate (CaCO 3).
