Objective: To prepare dehydroandrographolide self-emulsifying formulation and evaluate its quality. Method: Types of prescription accessories were screened by solubility test;With emulsifying effect
emulsification equilibrium time
particle size and distribution of this emulsions
accessories were determined by orthogonal test
and optimum prescription was determined by combining with ternary phase diagrams.After diluted
appearance
particle size
Zeta potential and stability of this formulation were investigated. Result: Optimum prescription of dehydroandrographolide self-emulsifying formulation was as following:mtween-80: mMCT:mglycerin=50:20:30
particle size of 23.7 nm
Zeta potential of -14.47 mV.Self-emulsifying speed was rapid
and it had good stability at room temperature for 3 months. Conclusion: This optimized preparation technology was simple with fast emulsifying time and small particle size
prepared self-emulsifying formulation was clear and transparent with stable quality.
