Abstract

Objective To study the optimum flavonoids extraction process of Elaeagnusangustifolia L. with ethanol. Methods The best condition of extraction process of flavonoids was investigated by orthogonal design. Results The ratio of extraction on this condition was 2.295 mg/g. Conclusion The optimum technological conditions attained by theorthogonal experiment was as follows:concentration of ethanol 70%, extraction temperature 45 ℃, extraction time 30 min and the ratio of Elaeagnusangustifolia L. to extractant 1∶16.
