利用煅石膏吸水固化性质使难于干燥的中药水或醇浸膏迅速干燥,制成的颗粒疏松,利于有机溶剂提取。通过渗漉法可避免常规萃取时产生的乳化现象。临床证明,石膏固相提取法制备的东莨菪碱和白斑灵软膏与常规提取制备的没有差别,应用于有效成分的分离效果也好。本法简便、安全、无需特殊设备。 The use of calcined gypsum water absorption curing properties makes it difficult to dry the traditional Chinese medicine water or alcohol extract quickly dried, the resulting loose particles, which is conducive to the extraction of organic solvents. The seepage method can avoid emulsification that occurs during routine extraction. Clinically proven, the scopolamine prepared by the solid phase extraction method has no difference with conventional preparations, and the separation effect of the active ingredients is also good. This method is simple, safe, and does not require special equipment.
