摘要

目的：采用 HPLC 法测定并对比新疆黑果小檗根皮与根木质部中阿魏酸的含量,并优化其提取工艺条件。方法：①通过不同溶剂提取黑果小檗根皮、根木质部,根据其含量测定结果选定最优提取溶剂。②在单因素试验结果基础上,采用响应曲面法优化阿魏酸的提取工艺。结果：①确定乙醇提物中阿魏酸含量最高。②确定最佳提取条件。平行试验3 次,新疆黑果小檗根皮、根木质部中的阿魏酸在提取溶剂为 60%乙醇,提取温度为 50 ℃,料液比为 1∶15,提取次数为 3 次的提取条件下提取效率最高,其中,根皮中阿魏酸提取量 0.71%(RSD=1.24%),根木质部中阿魏酸提取量 0.32%(RSD=1.51%)。结论：本提取工艺稳定可行,提取效率较高。

Abstract

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.
