Abstract

Plants are adundantly and are very promisive to be used as source of drugs in many diseases or infections and also it is a main agents of antioxidants which prevents the oxidative stress that are caused by the free radicals. There are numerous studies based on the pharmaceutical and classification of medicinal plants throughout the world. Leaves, fruits, roots are most frequently plant parts used in many research and studies. Here the present study was aimed to evaluate the in vitro antioxidant activity of aqueous and ethanol leaf extracts of Andrographis paniculata Nees and Rhinacanthus nasutus Kurz. Antioxidant is a substance which is used to prevent some types of cell damage in the body. Determination of their in vitro antioxidant activity were carried out by using methods such as DPPH (2,2-diphenyl-1picrylhydrazyl assay), ABTS (2,2′-azinobis (3-ethylbenzothiazolin 6-sulfonic acid assay), FRAP (ferric reducing antioxidant power assay) and SOD (super oxide anion scavenging) assay, H2O2 (hydrogen peroxide radical scavenging) assay. Moreover the ethanolic leaf extracts showed best antioxidant activity than the aqueous leaf extracts. Experimental results reveals that the leaves of A. paniculata have potent antioxidant and free radical scavenging activity than R. nasutus. Further investigation must be done for these two medicinal plants for the discovery of the bioactive compounds.
