Objective: To investigate the effects of different processing methods on the content of rutin and tannin in Sophora japonica herb medicine (Chinese herb medicine name: Huai Mi or Huai Hua).
Methods: Huai Mi was processed with different methods. Tannin content was determined using potassium permanganate titration method. Rutin content was quantified using ultraviolet spectrophotometry.
Results: The tannin content was the highest in stir-fried-to-coke samples (1.87%), while the highest rutin content was observed in stir-fried-to-yellow samples (0.134%). The stir-fried-to-ash samples had the lowest contents of both rutin and tannin.
Conclusion: Processing methods critically impact the contents of bioactive compounds in Sophora japonica herb medicine. Optimizing these methods may enhance medicinal efficacy and utilization
