Abstract
The extraction of flavonoids from Yaxuenuo was studied by the five factors of ethanol concentration,extraction temperature and time,material/liquid ratio and pH in this article.The orthogonal experiments were followed by every single factor identified in the best conditions,the optimal conditions for extraction of flavonoids from Yaxuenuo as follows:extracting temperature 60℃,ethanol concentration 75%,material/liquid ratio 1:100 and pH 2 for an extraction duration of 2.5 h,the total flavonoids yield obtained from Yaxuenuo was 9.52mg/g.
