“…The antioxidant activities of synthesized compounds (2a-e) and vanillic acid evaluated spectrophotometrically following the procedure of free-radical DPPH scavenger and Ferric ion Reducing Activity Potential (FRAP) as reported previously, with slight modification. 5,[17][18] Quercetin was used as a standard.…”

We synthesized five new Mannich bases compounds from vanillic acid and evaluated for their antioxidant activities using a free-radical DPPH and FRAP methods. The compounds' structures were confirmed based on infrared, proton NMR, carbon NMR, and mass spectra. In this study, the compound 5-(pyrrolidin-1-ylmethyl)vanillic acid (2e) showed the best free-radical scavenger activity, while compound 2-[(diethylamino)methyl]vanillic acid (2c) showed the best as a ferric reductant. Mannich bases enhanced the free-radical scavenger activity but decreasing the ferric reduction potential of the parent compounds. The compounds were found to be moderate antioxidant agents.

“…Diverse sustainable herbs with antioxidant properties have been successfully employed in scavenging these dangerous radicals as a protective measure against organ damage and for ameliorative purposes. 108,109 Particularly, spices such as ginger and turmeric are generally accepted since they are with less negative side effects and are therefore good candidates for nutraceutical development.…”

contaminants in the environmental systems are the heavy metals which gain access into our environment through natural and human activities such as soil erosion and runoffs , mining and rock weathering, indiscriminate disposal of industrial effluents, sewage discharge, unguided use of pesticides, etc. 1 Although some of these metals are "essential", however, above their permissible limits, such metals become harmful to the body. The WHO permissible limit for cadmium, chromium, copper, lead, manganese and nickel in drinking water are 0.003, 0.05, 2.00, 0.01, 0.50, and 0.02 mg/L, respectively. 2 Above these levels, these metals are no longer beneficial. When aquatic animals ingest heavy metal-contaminated water, they naturally bio-accumulate the metals. Similarly, when plants are irrigated with such water, heavy metal accumulation occurs. The eventual consumption of these is dangerous as it consequently leads to the development of various life-threatening diseases such as cancer and organ damage among others. The threat of heavy metal poisoning is higher for people in rural areas. Particularly, people in neglected parts of developing nations are more prone to such poisoning because of ignorance and lack of potable water supply. 3
