Free radicals are known inducers of cellular and tissue pathogenesis leading to several human diseases such as cancer, inflammatory disorders, as well as in aging processes. Antioxidants provide protection to living organisms from damage caused by uncontrolled production of reactive oxygen species and the concomitant lipid peroxidation, protein damage and DNA strand breakage. There has been an increased concern over management of agri-horticultural waste todevelop useful product and to prevent environment pollution. Some selected agri-horticultural wastes like left over residuals from Trigonella foenum-graecum (Fenugreek), Brassica rapa(Turnip), and Brassica oleracea (Cabbage) were studied for their antioxidant activity alone and in combination to find synergistic effect if any and to determine their nutraceutical potential.The antioxidant activity of residuals of fenugreek, turnip, and cabbage was 816, 864 and 545.6 µmTE/g whereas the antioxidant activity of their synergistic combinations of (fenugreek plusturnip), (fenugreek plus cabbage), (turnip plus cabbage) and all the three (fenugreek plus turnip plus cabbage) was found to be 808, 1140, 2456 and 1048 µmTE/g respectively. The synergy fold was found to be maximum in combination of turnip and cabbage with 3.4 fold. Thepresent studies showed that agri-horticultural wastes have tremendous potential to be used as nutraceutical in the prevention and management of free radicals, oxidative stress and associateddisorders.
