| Abstract: | The optimal conditions of flavonoid extraction from lotus leaf by solvothermal method and its antioxygenation were studied.The results showed that the best technical conditions for flavonoids extraction could be obtained with ratio of raw materials and solution as 1:40,60% alcohol and extraction period for 2.5h,temperature at 80℃.The antioxygenation of the flavonoids was studied in the soybean oil.The graph of POV showed that the flavonoid was a good antioxidant. |
