[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2.5h.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.

[Objective] 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.
