| 摘 要： | 目的]利用碱解农林废弃物制备阿魏酸和对香豆酸。方法]对4种农林废弃物(花生壳、玉米秸秆、小麦秸秆、玉米芯)进行比较,发现玉米芯最适合用于提取阿魏酸和对香豆酸。考察不同氢氧化钠浓度、固液比(玉米芯/碱液)、提取温度、提取时间对玉米芯中阿魏酸和对香豆酸提取量的影响。结果]提取玉米芯中阿魏酸的最佳工艺条件为:氢氧化钠浓度为0.5 mol/L,固液比(玉米芯/碱液)为1∶30 g/ml,提取温度为50℃,提取时间为2.5 h。在此条件下,阿魏酸的提取量最高为14.05 mg/g,对香豆酸的提取量为21.12 mg/g。结论]研究可为提高玉米芯的附加值利用提供依据。

| Abstract: | The ferulic acid and p-cumaric acid were produced from agricultural residues by alkaline hydrolysis. Method]Corn cob was found to be the best through the comparison of alkaline hydrolysis of peanut shell,cornstalk,wheat straw and corncob. Effects of different sodium hydroxide concentration,solid-liquid ratio,extraction temperature and time on ferulic acid; p-cumaric acid were investigated.Result]Optimal hydrolysis conditions（NaOH concentration of 0.5 mol/L,solid/liquid ratio of 1∶30 g/ml,hydrolysis temperature of 50 ℃,hydrolysis time of 2. 5 h） ensured the production of hydrolysates with relatively high contents of both ferulic acid（14. 05 mg /g） and p-coumaric acid（21. 12 mg /g）. Conclusion]The study can provide basis for improving added value utilization of corn cob. |
