Optimization of Autoclave and Microwave Assisted Alkaline Hydrolysis for Release of Ferulic Acid from Biomass
Ferulic acid is phenolic acid which wxists in plant cell walls and has many physiological properties including antioxidant, antimicrobial, anticancer and anti-inflammatory activities. In this study, ferulic acid was obtained from lignocellulosic biomass by autoclave assisted alkaline hydrosis (AAA)...

Ferulic acid is phenolic acid which wxists in plant cell walls and has many physiological properties including antioxidant, antimicrobial, anticancer and anti-inflammatory activities. In this study, ferulic acid was obtained from lignocellulosic biomass by autoclave assisted alkaline hydrosis (AAA) and the process was compared with microwave assisted alkaline hydrolysis (MAA). The results from the phenolic analysis of lignocellulosic biomass by HPLC showed that when lignocellulosic biomass was hydrolyzed by 0.5 M NaOH for 15 min in the autoclave, the corn husks and corn cobs released high amounts of ferulic acid. The effects of applying different concentrations of NaOH (0.25, 0.5, 1.0, 1.5 and 2.5 M) and hydrolysis time (5, 15, 30, 45, 60, 75 and 90 min) in order to release ferulic acid using an autoclave and a microwave were investigated.
