摘要

[Objectives]This study was conducted to investigate the extraction process of quiona(Cheuopodium quinoa)leaves.[Methods]Firstly,single factor experiments were carried out with the volume fraction of ethanol,extraction time,extraction temperature and liquid-to-material ratio as factors.Based on the single factor experiments,a response surface test was designed by the central composite design method of Design-Expert software to establish a mathematical model.[Results]The optimal extraction conditions of quinoa flavonoids were obtained as follows:the ethanol volume fraction of 70%,the liquid-to-material ratio at 30∶1,the extraction time of 100 min and the extraction temperature at 60℃.[Conclusions]The results of the study are stable with small deviation,and can provide reference for related processes.
