Objective: To establish quality standard of bran. Method: A intuitive description method was adopted to describe appearance of bran.Moisture
total ash
acid-insoluble ash and water-soluble extract were determined by methods in the 2015 edition of Chinese Pharmacopoeia.UV spectrophotometry was employed to determine the content of total flavonoids in bran with detection wavelength at 510 nm. Result: Ten batches of bran were different in character
total ash
acid-insoluble ash
water-soluble extract and the content of total flavonoids.There was a good linear relationship of total flavonoids (as rutin) in 3.232-16.16 mg·L-1 with r of 0.999 5
the average recovery was 99.31%. Conclusion: This method is simple and reproducible for quality control of bran.Moisture
total ash
acid-insoluble ash
water-soluble extract and the content of total flavonoids (as rutin) in bran should be ≤14.0%
