Abstract
In order to confirm the best extract process conditions,the effect of the factors and the interac-tions among them on the extraction of flavonoids in the peel of Henan tiegun yam was researched by re-sponse surface method. The factors were extraction time,solid - liquid ratio,sieving mesh number and ethanol volume concentration. The optimal factors confirmed by software Minitab 16 were adjusted to eth-anol volume fraction 79%,solid - liquid ratio 0. 023 g / mL,extraction time 75 min and sieving mesh number 120 mesh. The average yield was 0. 338 2 mg / g determined by verification test,close to the pre-dicted value. The test data was stable,which indicated that the regression model could predict the yield rate of flavonoids in the peel of Henan tiegun yam.关键词
