| Abstract: | The method of extracting total quantity of flavone from Amaranthus spinosus and the effect of concentration,time,temperature,ratio of material to liquid was discussed.Meanwhile,the optimized conditions for extraction were determined by orthogonal analysis.The best parameters were 40% ethanol as extractant,temperature 60℃,extraction time 2h,ratio of material to liquid 1:20.In this case,the rate of extraction could reach up to 2.83mg/g. |
