Influence of nitrogen fertilizer micro-dosing on phenolic content, antioxidant, and anticholinesterase properties of aqueous extracts of three tropical leafy vegetables
2018
Substituting synthetic antioxidant food additives with naturally occurring plant antioxidants could promote the production of safer food systems. The combined use of organic manure with urea fertilizer led to enhanced antioxidant and anti-AChE activities of the leaf polyphenolic extracts. This detailed paper demonstrates how vegetable leaf polyphenolic compounds show free radical scavenging and other antioxidant properties that are comparable to those of butylated hydroxytoluene, a synthetic antioxidant agent. Results indicate that the vegetable leaf extracts are potential agents that can be used both as effective food preservatives and bioactive agents against neurodegenerative diseases.
