ABSTRACT
OBJECTIVE: To optimize the formulation of self-microemulsion containing total saponins from Lysimachia capillipes by central composite design-response surface methodology. METHODS: Based on the study of solubility, compatibility test and ternary phase diagram, central composite design-response surface methodology was adopted to optimize the best prescription with the emulsifying time, particle size, and Zeta pontential as indexes, physicochemical properties of this self-microemulsion were also determined. RESULTS: Optimum formulation was 12.93% of ethyl oleate, 57.25% of Kolliphor RH40, 29.82% of Transcutol. The a verage particle size, polydispersity index, Zeta pontential and drug loading of self-microemulsion containing total saponins from Lysimachia capillipes were 23.0 nm, 0.160, -20.28 mV and 10.52 mg·g-1.CONCLUSION: With good predictability, this methods can be used for the formulation optimization of self-microemulsion loaded total saponins from Lysimachia capillipes.
