Summary: | Flavonoids are plant secondary metabolites with a low molecular weight polyphenolic structure with nutraceutical, medical and therapeutic significance. Flavonoids are synthesized in all parts of the plant. They provide colour, smell and taste to fruits and seeds, and make them appealing to insects, birds, and mammals, which helps with pollen and seed transmission. Due to the combination of iron-chelating and free radical scavenger properties and the inhibition of enzymes such as lipoxygenase, cyclooxygenase, myeloperoxidase, nicotinamide adenine dinucleotide phosphate oxidase and xanthine oxidase, flavonoids are strong antioxidants. Flavonoids increase coronary vasodilation, diminish platelets coagulation, prevent LDL oxidation, reduce inflammation and act as anti-apoptotic and anti-necrotic agents. Cyanobacteria and algae possess unique secondary metabolites, including flavonoids with potential biological activities. Isolation and identification of these flavonoids from cyanobacteria as well as algae are expected to aid in the development of therapeutic and nutraceutical agents. |
