Objective To establish a new colorimetric assay method for the determination of total ginsenoside in Ginseng health foods.Methods Samples were purified by macroporous adsorption resin,the reaction of anthrone with glycon in ginsenosides was assayed by colorimetric method.Ginsenoside Re was used as a reference material.Results There was a good linearity in the range of 5-200 μg/ml of ginsenoside,the regression equation was y=0.369+0.994x,the correlation coefficient r=0.999 5.The recovery rate was...
