Abstract:
Objective: To study the comprehensive utilization of Herba Ephedrae resources during the extraction process of ephedrin, that is the extracting of porphyrin compound.Methods: The process conditions for preparing sodium copper porphyrin were optimized by the two preparation processes and twice orthogonal tests. Results: Herba Ephedrae was powdered, steeped and boiled in alcohol, saponified, then extracted with xylene. The ephedrin was extracted from the upper layer of xylene extraction solution and sodium copper porphyrin was obtained from the lower layer by copper substituton, acidulation and alkalization. Conclusion: The optimum preparation process for producing sodium copper porphrin of Herba Ephedrae which is superior to porphyrin in the stability and colour is ascertained.
