ABSTRACT
Objective To prepare silymarin phospholipids complex(SM-PC) and investigate its physicochemical properties. Methods On the basis of single-factor tests, the drug-lipid ratio, drug concentration and reaction temperature were selected as the factors of the central composite design and response surface methodology in the preparation of SM-PC by solvent volatilization, and the best process was optimized with the compound rate as the index. And its in vitro dissolution was measured. Results The optimum preparation technology of SM-PC was as follows acetone was used as compound solvent, the concentration of SM was 8.0 mg/ml, the mass ratio of SM to phospholipid was 1∶1.8, the reaction temperature was 56 ℃ and the recombination rate was(95.15±1.55)% with deviation of less than 3%. The in vitro dissolution test showed that the dissolution of SM-PC was close to 90% in 60 min. The dissolution behavior of main component of silybin was similar to that of silymarin capsules(Legalon ®), which was higher than SM-API. Conclusion SM-PC was successfully prepared by central composite design response surface method, which significantly improved the dissolution and laid a foundation for the study of subsequent preparations.
