Title Study on Preparation Process of Hematoporphyrin and Cyclodextrin Inclusion Compound

Abstract To study the preparation process of the inclution compound of hematoporphyrin and cyclodextrin。 The best cyclodextrin was optimized according to solubility, Drug loading and encapsulation efficiency。 Hematoporphyrin and cyclodextrin inclusion compound was prepared by saturated aqueous solution method and grinding method, the best preparation process was optimized with single factor experiment, and was characterized by ultraviolet spectroscopy (UV), Fourier infrared spectroscopy (FI-IR) and thermal gravimetric analysis (TGA)。 The results showed that inclution compound was prepared with β-cyclodextrin，and the best method was saturated aqueous solution method。 The advantages were high Drug loading and encapsulation efficiency, saving conclution materials and applying to mass production for industrialization。 The optimum preparation conditions of satur- ated aqueous solution method were as follow :the ratio of Hematoporphyrin to cyclodextrin was 1:3, stirring temperature was 50℃, stirring time was 3 h。 Drug loading was 17。32% , encapsulation efficiency was 91。99%。 Hematoporphyrin- cyclodextrin inclusion compound was formed by character。
