Study on Extraction of Flavanoids from Vaccinium uliginosum L.

Abstract

Abstract: Based on contrast analysis,some factors that affect extracting rate of flavanoids from Vaccinium uliginosum.L were studied. The orthogonal design of L9(34)was used to select the optimal technological conditions for extracting flavanoids from leaves of Vaccinium uliginosum L .with the internal reflux method,and the optimal parameters were as followtemperature 80 ℃,the ratio of 1/50,ratio of material to water 1:50,concentration of alcohol 80%,time 25min.

Key words: , Vaccinium uliginosum.L； total flavonoids； internal reflux method； orthogonal test design；
