A HERBAL FORMULATION AND ISOLATION OF PHARMACOLOGICAL ACTIVE AND FREE RADICALS SCAVENGING IMPACT OF MEDICINAL PHYTOCONSTITUENTS ON HUMAN AGEING, DIABETES, HYPERLIPIDEMIA, HIV AND SEXUAL DYSFUNCTION

摘要

The term "antioxidant" refers to any molecule capable of stabilizing of deactivation free radicals before they attack cells. These are in particular the primary "antioxidant". There are also molecules deserving the "antioxidant" team, because they act as chelating agents binding metal ions (redox activity). To protect the cells and organ systems of the body agamst reactive oxygen species, humans have evolved a highly complex antioxidant protection system. These include antioxidant enzymes that catalyze free radical quenching reactions, and diet-derived antioxidants like ascorbic acid, Vitamin E, carotenoids, polyphenols and other low molecular weight compounds such as α-lipoic acid.
