目的研究水飞蓟宾的理化性质,为设计优良的处方奠定基础。方法采用高效液相色谱法测定水飞蓟宾在不同溶剂中的平衡溶解度,采用摇瓶法测定水飞蓟宾在正辛醇-水和正辛醇-缓冲液体系中的油水分配系数,并进行破坏性试验等处方前研究。结果水飞蓟宾在25 ℃水中的平衡溶解度为1.352 mg/L,在乙腈中溶解度最大,在碱性缓冲液中溶解度增大,且加入表面活性剂能增加水飞蓟宾在水中的溶解度,其中十二烷基苯磺酸钠对水飞蓟宾的增溶能力最强;水飞蓟宾的表观油水分配系数为61.39;水飞蓟宾在酸、碱、氧化性和还原性溶液中均不稳定。结论本研究结果可为水飞蓟宾新制剂的设计提供参考。

Objective To study the physical and chemical properties of silibinin; To lay foundation for optimal formulation design.Methods The high performance liquid chromatography method was used to detect the equilibrium solubility of silibininin in various solutions. The partition coefficients of silibinnin in the n-octalution-water and n-octalution-buffer solution systems were determined by shaking flask method. The destructive tests were carried out on silibinin.Results The equilibrium solubility of silibininin at 25℃ was 1.352 mg/L in water and the...
