| Abstract: | The total flavonoids in tarragon were determined by Et O H-K2HPO4 two-phase system, dosage of salt and ethanol effect on aqueous two-phase system were investigated. The optimal aqueous two-phase extraction conditions were： ethanol consumption was 7.0ml, K2HPO4 dosage for 1.5g, in these extraction conditions, the contents of total flavonoids from tarragon were determined by UV spectrophotometry. |
