摘要
目的:研究不同O/W型微乳对黄芩苷和葛根素的增溶作用的影响。方法:采用不同油相、乳化剂、助乳化剂及其比例,制成不同配方的微乳,进行理化性质的测定和评价,并对黄芩苷和葛根素在不同溶剂和微乳中的溶解度进行测定。结果:11种微乳配方可形成较好的微乳,各配方对黄芩苷和葛根素均有增溶作用。与水中的溶解度相比,黄芩苷可被增溶5~15倍,葛根素可被增溶3~4倍。结论:微乳对于中药有效成分的增溶具有良好的应用前景。
Objective: To study the effect of O/W Microemulsion in enhancing solubility of haicalin and puerarin. Method: The Pseudo-ternary phase diagram was employed to selected the formulations of O/W microemulsion. The partical size of microemulsion, and solubility of haicalin and puerarin in water, oil phase, surfactant, microemulsion and alcohol were determined, respectively. Result: 11 types of microemulsion formulations have the effect in enhancing the solubility of baicalin and puerarin; the solubility of Baicalin in microemulsion is higher as 5-15 times than it in water, the solubility of Puerarin in microemulsion is higher as 3 -4 times than it in water. Conclusion: Microemulsion is good in enhancing solubility of effective compounds extracted from Chinese medical herbs.
