Antioxidants are essential substances which contribute to benefits of moringa.
In fact, they are well-known for their incredible effects on fighting against free radicals inside the body system.
It is easy for high content of free radicals to trigger oxidative stress.
It is one of the most common deciding factors which may cause chronic issues such as cardiovascular disease or type 2 diabetes
There are numerous types of antioxidant substances in moringa leaves
Beside vitamin C and beta-carotene, quercetin and chlorogenic acid are telling examples of antioxidants in moringa.
While quercetin may reduce blood pressure, chlorogenic acid can lead to blood sugar regulation
Women participated in a study and moringa leaves could regulate blood antioxidant levels
By lowering oxidation, moringa leaf extract can lengthen the shelf life of meat
As a result, it is able to act as a food preservative.
Antioxidants play an important role in inhibiting and scavenging free radicals, thus providing protection to human against infections and degenerative diseases. Current research is now directed towards natural antioxidants originated from plants due to safe therapeutics. Moringa oleifera is used in Indian traditional medicine for a wide range of various ailments. To understand the mechanism of pharmacological actions, antioxidant properties of the Moringa oleifera leaf extracts were tested in two stages of maturity using standard in vitro models. The successive aqueous extract of Moringa oleifera exhibited strong scavenging effect on 2, 2-diphenyl-2-picryl hydrazyl (DPPH) free radical, superoxide, nitric oxide radical and inhibition of lipid per oxidation. The free radical scavenging effect of Moringa oleifera leaf extract was comparable with that of the reference antioxidants. The data obtained in the present study suggests that the extracts of Moringa oleifera both mature and tender leaves have potent antioxidant activity against free radicals, prevent oxidative damage to major biomolecules and afford significant protection against oxidative damage.
