Optimization of γ-Cyclodextrin Inclusion Technology for Bifenzate by Orthogonal Test

The optimum inclusion process conditions for bifenzate using γ-cyclodextrin were studied.The inclusion technology was optimized by orthogonal test with the mole ratio of γ-cyclodextrin to bifenzate,inclusion time,inclusion temperature as factors and with the yield and the inclusion rate as indexes for evaluation.The optimum inclusion conditions were established as the follow: n(γ-cyclodextrin)∶n(bifenazate)=1∶1,the inclusion temperature at 30℃ for5 h.The technology was effective with high yield and inclusion rate.
