| Abstract: | Objective] The aim was to study the extraction technology of total flavonoids from buckwheat in Weining City of Guizhou Province. Method] The best extraction techniques and conditions for total flavonoids were optimized with orthogonal experiment.Taking the yield of total flavonoids as indicator,the content of total flavonoids was determined with spectrophotometry. Result] The optimum extraction conditions were as follows:with ethanol as the solvent,liquid-solid ratio 10:1,extraction time 2 h,extraction ... |
