| Abstract: | A kind of aqueous two-phase system composed of PEG,（NH4）2SO4 and water was used to separate and purify total flavonoids from lotus leaves.The results showed that the best ATPS was composed of 25 % PEG4000 and 10 %（NH4）2SO4,and addition of sample was 3 mL at room temperature.Under this conditions,the yield can reach to 97 %. |
