Objective:To determinate and compare the content of ferulic acid in root bark and root xylem of Xinjiang Berberis heteropda Schrenk by HPLC,and optimize the extraction process conditions. Methods①The root bark and root xylem of Berberis heteropoda Schrenk were extracted with different solvents,and the optimum extraction solvent was selected according to the results of contents determination. ②Based on the results of single factor test,the extraction process of ferulic acid was optimized by response surface methodology. Results:①The content of ferulic acid in the ethanol extraction was the highest. ②The optimum extraction conditions were confirmed after three times parallel test. The extraction efficiency was maximum when the extraction solvent was 60% ethanol,the extraction temperature was 50 ℃,the liquid ratio was 1:15 and the times of extraction were 3. The extraction amount of ferulic acid was 0.71%(RSD=1.24%)in the root bark and 0.32%(RSD=1.51%)in the root xylem. Conclusion:This extraction process is stable and feasible with higher extraction efficiency.
