Free radicals are atoms or molecules that have one or more unpaired electrons on its outer orbital, highly reactive, and could damage cell inside human body. Antioxidants are the substances which inhibit oxidation, which have the ability to remove the potentially damaging oxidizing agents in a living organism. Many phytochemicals present in the plants are able to reduce or prevent the oxidative damage to the human cells which can cause even cancer in humans. It is highly vital to know about the antioxidant activities of each plant and the phytocompounds responsible for that. In this study, the DPPH free radical scavenging activity of the extracts of Pomegranate and Citrus (Lemon) is analyzed. And we found Citrus peel extract 2, 2-Diphenyl-1-picryl-hydrazyl (DPPH) assay activity better on comparing Pomegranate peel extract.

  This review brings out some medicinal plants that have therapeutic potential due to the presence of natural antioxidants. Majority of their antioxidant activity is due to bioactive compounds viz. Flavonoids and Polyphenolic compounds. The Present research reveals that Flavonoids and polyphenolic compounds activity have important effects on cancer chemoprevention and chemotherapy. Numerous mechanisms of action have been recognized, along with inactivation cancer, antiproliferation, and cell cycle arrest, stimulation of apoptosis and inhibition of angiogenesis. This work has particularly enhanced the function of antioxidants activity of Flavonoids for cancer research. Key word: Flavonoids, Antioxidant, Free radical and Cancer research
