Original Text: Ferulic Acid

Ferulic acid 3-(3-methoxy-4-hydroxyphenyl)-2-propenoic acid is one of the major hydroxycinnamic acid found in the cell wall of graminaceous plants such as paddy straw, wheat straw, corn cob and others cereal straw. This compound is considerable interest for applications in the food, health, cosmetic and pharmaceutical industries. This hydroxycinnamic acid and other derivative are found covalently linked to polysaccharides by ester bonds and to components of lignin by ester or ether bonds. Determination of ferulic acid in straw has been carried out through alkaline hydrolysis treatment and optimized through response surface methodology. A 23 full factorial design with three triplicates at the centre point was used to investigate the extraction process with three variables : NaOH concentration (0.5-2M), temperature (25-70oC), and reaction time (1-3 hrs) on the alkaline hydrolysis process. Throught this study, range of the crucial parameter involved during the extraction process can be obtained.

Ferulic acid, 3-(3-methoxy-4-hydroxyphenyl)-2-propenoic acid, is one of the major hydroxycinnamic acids found in the cell walls of graminaceous plants, such as paddy straw, wheat straw, corn cob and other cereal straws. This compound has considerable interest for applications in the food, health, cosmetic and pharmaceutical industries.

This hydroxycinnamic acid and other derivatives are found co-valently linked to polysaccharides by ester bonds and to components of lignin by ester or ether bonds. Determination of ferulic acid in straw has been carried out through alkaline hydrolysis treatment and optimized through response surface methodology. A 23 full factorial design with three triplicates at the centre point was used to investigate the extraction process with three variables : NaOH concentration (0.5-2M), temperature (25-70oC), and reaction time (1-3 hrs) on the alkaline hydrolysis process. Through this study, the range of crucial parameters involved during the extraction process can be obtained.
