Abstract:
The ethanol extraction of flavonoid glycosides in Rhodomyrtus tomemtosa was discussed by single factor and orthogonal experiments. The influential factors were investigated and the optimal weight ratio of Rhodomyrtus tomemtosa to ethanol, the extraction time, temperature and ethanol concentration were shown to be 1:40, 80 ℃, 60% and 2.5 h, respectively.
