摘要

目的 制备和厚朴酚环糊精纳米海绵,考察环糊精纳米海绵对和厚朴酚的增溶作用,并对其理化性质进行初步考察。方法 采用β-环糊精与碳酸二苯酯合成环糊精纳米海绵,并用红外光谱法(FT-IR)和热分析法(DSC)进行验证。结果 和厚朴酚环糊精纳米海绵在DSC中无和厚朴酚的特征吸收峰,FT-IR中1 780 cm-1左右出现新的羰基峰。体外释放实验中和厚朴酚环糊精纳米海绵5 h的累积释放为88.57%,而和厚朴酚混悬液仅为46.55%。纳米海绵使和厚朴酚在水中的溶解度增加了8.87倍。结论 成功制备了和厚朴酚环糊精纳米海绵,显著提高了和厚朴酚的溶解度。

Abstract

OBJECTIVE To prepare the honokiol-loaded β-cyclodextrin-based nanosponges (HK-NSP) and investigate their physicochemical properties. METHODS β-Cyclodextrin-based nanosponges (NSP) was obtained by reacting β-cyclodextrin with diphenyl carbonate and the effect of NSP on honokiol solubilization was investigated. Moreover,NSP and HK-NSP were validated by FT-IR and DSC. RESULTS The FT-IR of HK-NSP showed the presence of the carbonate bond as evidenced by a peak at 1 780 cm-1,and the DSC of HK-NSP did not showed the melting peak corresponding to drug fusion. The percentage of HK released from NSP after 5 h in phosphate buffer solution was 88.57%,and that from HK suspension was only 46.55%. Moreover,NSP showed 8.87 times solubilization efficiency for HK. CONCLUSION HK-NSP are successfully prepared,and the solubility of HK is improved by the NSP obviously.
