摘  要:
[Objective] To establish optimal extraction technology of polyphenols from Dioscorea opposita Thunb..[Method] Using content of polyphenols in Dioscorea opposite Thunb.as investigation index,the extraction conditions of total polyphenols from Dioscorea opposita were optimized by orthogonal test based on single factor test.[Result] The optimum extraction conditions were confirmed to be 50% acetone of extraction solvent(V/V),1:15 of the solid to liquid ratio(W/V),80 min of extraction duration,55 ℃ of extraction temperature and 2 times of extraction times.[Conclusion] This study offered theoretical references for the further research and development of Dioscorea opposita Thunb.polyphenols.
