【摘要】:目的制備丁苯酞-磺丁基-β-環(huán)糊精包合物,并考察其結構和性能。方法采用冷凍干燥法制備包合物,用紫外分光光度法測定其包合率、含量、溶解度、溶出度。通過薄層色譜法、紫外光譜法、紅外光譜法、差示掃描量熱-熱重聯用法,驗證包合物結構的形成。通過相溶解度法,確定最佳包合比例。通過溶出試驗考察形成包合物后丁苯酞溶出速率的變化。結果丁苯酞與磺丁基-β-環(huán)糊精可形成摩爾比為1∶1的包合物,包合率為(56.70±1.5)%,平均含量為(5.02±1.6)%。結論制備丁苯酞-磺丁基-β-環(huán)糊精包合物的方法簡單易行,并且可以有效提高丁苯酞在水中的溶解性和溶出速度。
[Abstract]:Aim to prepare butylphthalide-sulfonbutyl-尾-cyclodextrin inclusion complex and investigate its structure and properties. Methods the inclusion complex was prepared by freeze-drying method. The inclusion rate, content, solubility and dissolution were determined by ultraviolet spectrophotometry. The formation of inclusion complex was verified by thin layer chromatography, ultraviolet spectroscopy, infrared spectroscopy and differential scanning calorimetry-thermogravimetry. The optimum inclusion ratio was determined by phase solubility method. The dissolution rate of butylphthalein was investigated by dissolution test after the inclusion compound was formed. Results the inclusion complex with molar ratio of (56.70 鹵1.5)% and (5.02 鹵1.6)% was formed with the molar ratio of butylphthalide and sulfobutyl-尾-cyclodextrin (molar ratio) of (56.70 鹵1.5)% and (5.02 鹵1.6)%, respectively. Conclusion the method for the preparation of butylphthalide-sulfonbutyl-尾-cyclodextrin inclusion complex is simple and feasible, and it can effectively improve the solubility and dissolution rate of butylphthalide in water.
