Abstract: Objective: To establish a determination method of ferulic acid in wheat bran by derivatization combined with spectrophotometry. Methods: Ferulic acid was analyzed spectrophotometrically at 720 nm. The color-developing agent was the mixture of 0.6 g/100 mL FeCl3 and 0.9 g/100 mL K3Fe(CN)6] (1:0.9). Results: A good linear relationship in the concentration range of 2.36-14.16μg/mL for ferulic acid (r = 0.9996) was observed, and the detection limit of this developed method was 0.022μg/mL. The average recovery rate of this method was 103.1%. Conclusion: This developed method is characteristics of simple operation, accurate results and high average recovery rate, which is suitable for the determination of ferulic acid in wheat bran.

Key words: wheat bran, ferulic acid, derived spectrophotometry
