A new colorimetric method for determination of diosmin is proposed. The method is based on formation of a chromophore by the flavonoid in presence of 75% (v/v) HCl showing maximum absorbance at 405 nm. The technique with linearity over 10 through 80μg flavonoid (r ± s.e. = 0.9994 ± 0.0008, b±s.e. = 0.0089 ± 0.0001, COV ± s.e. = 2.8 ± 0.5, n= 6 each) has been compared with standard aluminium chloride method and a modified version that utilizes aluminium chloride for primary complexation of the… Expand
