“…Oxidative damage to erythrocytes is manifested as increased haemolysis due to lipid peroxidation. It has been reported that phytochemicals can protect erythrocytes from oxidative damage caused by H 2 O 2 28 . In our present study, we found that the ethanolic extract of the medicinal plants could reduce the effects of oxidative stress induced by exposure to H 2 O 2 more than aqueous one as manifested by an increase in percentage haemolytic inhibition at the concentration of 3.3 ug/ml.…”

Antioxidants from plant sources have gained acclaim as an excellent source for living a healthy life in recent times. The present study investigates comparative quantitative characterization of phytochemicals, invitro antioxidant and anti-hemolytic activities among aqueous and ethanolic extracts of four Indian medicinal plants viz. Berberis aristata, Cedrus deodara, Vitex negundo and Tinospora cordifolia. Quantitative estimation of phenolics, flavonoids, and alkaloids was done by colorimetric estimation. In-vitro antioxidant capacities were evaluated by hydrogen peroxide radical scavenging assay and ferric reducing antioxidant potential assay, while total antioxidant capacity was evaluated through phosphomolybdate assay. Anti-haemolytic activity of plant extracts was assessed using H 2 O 2 induced hemolysis of human RBCs. The aqueous extract of V. negundo and ethanolic extract of C. deodar resulted in significantly higher phenolic content amongst all plant extracts. The greatest flavonoid content was observed with an aqueous extract of V. negundo, and ethanolic extract of C. deodara demonstrated the highest alkaloid content. High antioxidant capacities were reported for the ethanolic extract of V. negundo and C. deodara. The ethanolic extract of C. deodara afforded significant protection to human RBC against the free radical damaging effect of H 2 O 2 with 82.8 ± 0.231% hemolytic inhibition as compared to other plant extracts. The aqueous and ethanolic extracts of Tinospora cordifolia, Cedrusdeodara, and Vitex negundo are effective in scavenging free radicals and could be a potential source of natural antioxidants. Our future work will focus on the identification and validation of bioactive antioxidants for their use in modern medicine or food products.
