Evaluation of the Antioxidant properties of Tribulus rajasthanensis L.- A case study

Abstract

Free radicals are continuously generated in the body during normal metabolic processes and though exposure to environmental factors such as infectious agents, pollution, UV light and radiations. When these harmful free radicals are not neutralized by primary and secondary defence mechanism of body, oxidative stress occurs, which is the reasons for development of various diseases. Plants have many phytoconstituents including saponin, flavonoids and polyphenol with high antioxidants properties. To determination of antioxidant properties of Tribulus spp. extracts (methanol and aqueous) DPPH (1,1- diphenyl 2- picryl hydrazyl) method was used. Whereas DPPH free radical scavenging activity of methanol extracts revealed the strongest as compared to aqueous extracts.
