| Abstract: | Using heating circumfluence extraction method,the optimum extraction conditions of total flavonoids in Angelica keiskei Koidzumi were studied by single factor and orthogonal experiments.The optimum extraction conditions detected by Al(NO3)3 developing method were 60% ethanol concentration,1:30 of material and liquid ratio,100 min extraction time,extracted 2 times.Under these conditions,the extraction yield was 1.946%.The optimum extraction conditions detected by AlCl3 developing method were 80% ethanol concentration,1:40 of material and liquid ratio,100 min extraction time,extracted 1 time.Under these conditions,the extraction yield was 1.811%.The extract rate of total flavonoids was high and steady with this technology,which provides new evidence for the utilization of Angelica keiskei Koidzumi. |
