Objective: To prepare baicalin thermosensitive gels for external application through different mathematical models and evaluation indexes. Method: Taking poloxamer 407( P407) and poloxamer 188( P188) as gel matrices,gelation temperature was applied as a target to compare formulations of baicalin thermosensitive gels,which were optimized by all sample multiple linear regression model and central composite design-response surface methodology( CCD-RSM),while combination of gelation time and length were adopted...
