Objective：To optimize the conditions of volatile oils extraction and β-cyclodextrin inclusion from Yiqi Xifeng Capsules. Methods：The extraction rate was used as the evaluation indexes to optimize extraction conditions based on orthogonal design,and the transformation rate of the volatile oils in inclusion complex and the yield of inclusion complex were used as the evaluation indexes to optimize inclusion conditions based on orthogonal design. Results：The optimal extraction conditions were as follows：the volume mass of water to crude drug being 10∶1,soaked for 0.5 hours and stream distilled for 6 hours. The optimal inclusion conditions were as follows：the mass ratio of β-cyclodextrin to oil being 8∶1,inclusion temperature at 50 ℃,and stirring for 2 hours. Conclusion：The optimal conditions for the extraction of volatile oils and β-cyclodextrin inclusion are steady and feasible,stability is improved,could prepare volatile oil extraction and β-cyclodextrin inclusion from Yiqi Xifeng Capsules.
