| Abstract: | The concentration of flavonoids in Glycyrrhiza uralensis fisch was determined with ultravio-let spectrophtometry, the detective wavelength was 500 nm, the R2 of Standard curve was 0.999 4 and the relative Standard deviation was 0.20% with the average recovery of 100.20%. The result showed that the rate of veracity of this method was high and this provided the determination of Glycyrrhiza flavonoids of pharmacognostic and finished products a feasible method. |
