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 0.9994 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.

Key words: Glycyrrhiza uralensis fisch, flavonoid, ultraviolet spectrophotometry
