| Abstract: | Objective To explore the extraction technology of tea saponin aglycone from tea oil cakes. MethodsThe effective factors on the yield of tea saponin aglycone were evaluated with single factor and orthogonal test to determine the optimum extraction. Results The extraction rate was different under different hydrolysis conditions. The optimum conditions were as follows： the ratio of liquid to solid was 20 ：1（mL ：g）, heated to reflux at 100 ℃ for 5 h in 70% ethanol with 2.0 mol·L^- 1 sulfuric acid, and the average yield of tea saponin aglycone was 10.80%. ConclusionThe method is simple and practical with high yield of tea saponin aglycone. |
