Objective: Excessive production of reactive oxygen species leads to oxidative stress. Antioxidants can prevent or retard the oxidation caused by free radicals and sufficient intake of antioxidants is supposed to protect against diseases. Candidate play  Methods: The leaf extracts of these plants were exposed to a battery of free radical scavenging assays like DPPH, ABTS, hydrogen peroxide, superoxide and nitric oxide to determine the free radical scavenging activity.Results: It was observed that the Majoranahortensis leaves in methanolic extract showed maximum scavenging activity.Conclusion: Several plants with free radical scavenging activity have been identified, where Majoranahortensis is one such leave.

Hemidesmus Indicus

Objective: A number of Indian medicinal plants have been used for thousands of years in a traditional system of medicine. Hemidesmus indicus is an important member of the Asclepiadaceae family. It is an endemic to the southern Western Ghats, India. The aim of the study was to investigate the free radical scavenging activity of H. indicus. Methods: The aqueous and methanol leaf extracts of H. indicus were assayed for radical scavenging activity, using the stable free radical 2,2-diphenyl- 1-picryl-hydrazyl-hydrate and 2,2’-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid). Results: The results revealed that the IC50 values of aqueous extract of H. indicus were found to be higher than that of the other solvent extracts. The free radical scavenging activity of the plant extracts may be due to the presence of phytoconstituents. Conclusion: In all the methods, the aqueous extract has exhibited the good scavenging activity and this arises that the plant has a potential antioxidant agent.

Whole Plant

Methanolic extract of the whole plant of Cyanthillium cinereum (L) H.Robwasevaluated for free radical scavenging activity by using Nitric oxide scavenging activity (NO) and Reduction of 1, 1-Diphenyl -2-Picryl Hydrazyl (DPPH) free radical scavenging activity. Throughout the studies the plant extract showed potent antioxidant activity and the activity was found to be concentration dependent which may be attributed to the high flavonoid content of the plant. Keywords: Cyanthillium cinereum (L) H.Rob, DPPH, NO.
