Objective: To investigate the method of content determination of ferula acid extraction and isolation in rice bran. Methods: Extraction technology: 1% sodium hydroxide solution with ethanol in the ratio of 4:1 for mixed, extraction of 6h at 80 ℃, Solid-liquid ratio was 1:8, antioxidant was 0.2g/L sodium sulfite. Method for the determination of the content: HPLC. Results: HPLC detection confirmed ferulic acid concentration has good linear relationship between 1.0~5.0ug/ml, r=0.9996, the rate of recovery was 99.8%. Conclusion:The result of HPLC for the determination of ferulic acid in rice bran extract is accurate, worthy of attention.
