Optimum flavonoids extraction from hawthorn fruits with surfactant

Objective:To optimum extraction technology of flavonoids from hawthorn fruits with surfactant.Methods:Single factor and orthogonal test were used to study the extraction conditions to extract flavonoids from hawthorn fruits.Results:The optimum extracting condition of extracting flavones from hawthorn was showed as follows,mass fraction of Tween 80 solution 1.5%;temperature of estraction 90℃;time of extraction 1 h;twice and the solid-liquid ratio 1:40(g/ml).Conclusion:The method is low cost,high yeild and no need for organic solvent and can be applied multipurposely.
