Hydroalcoholic extracts of Indian medicinal plants can help in amelioration from oxidative stress through antioxidant properties.

The in vitro study of the antioxidant properties of the hydroalcoholic extracts of various Indian medicinal plants can logically help to develop a better and safer way of amelioration from oxidative stress. As aimed, the present study has been done to estimate and thereby conclude regarding the antioxidant activities of a few Indian medicinal plants, viz., Terminalia chebula, Terminalia belerica, Emblica officinalis, Caesalpinia crista, Cajanus cajan, and Tinospora cordifolia. The extracts of the plants have been subjected to the evaluation of antioxidant properties through scavenging assays for reactive oxygen species like superoxide, nitric oxide, peroxynitrite, hypochlorous acid, singlet oxygen, etc. and measurement of TEAC values and other phytochemical parameters. The phenolic and flavonoid contents of each plant have been found to be correlated to their individual antioxidant activity. The results showed the hydroalcoholic extracts of the plants were efficient indicators of their antioxidant capacity thus concreting their basis to be used as natural antioxidant.
