| Abstract: | In order to clarify the flavonoids content in sweet potato leaves,the three-factor-three-level response surface experiment was established to select the optimum extraction scheme of flavonoids content from sweet potato leaves in this study. The results showed that optimum extraction scheme was as follows： alcohol concentration 52%, liquid material ratio 1：23 （w/v）, distilled 25 minutes, the content of flavonoids extracted from sweet potato leaves by the optimum extracting technology reached to 9.503 7%. This optimum scheme was stable in extraction amount, simple in operation and feasible in practice. |
