Sun radiations are the primary source of light & energy and the main causative factor in various skin conditions such as sunburn, photoaging, skin cancer development.These harmful effects may be due to the production of free radicals(Reactive oxygen species). Physical sun protection is not sufficient to get rid of such unwanted changes skin appearance and physiology. Now a day’s cosmetics and pharmaceuticals are added with natural sunscreens protecting reagents to provide health benefit apart from beautification. The aim of the present study is to formulate and evaluate natural sun protective topical formulation comprising methanolic extract of Butea monosperma (Lam.) flower, Neolamarckia cadama (Roxb.) leaves and Punica granatum (Linn) peel. The formulated cream was evaluated for its Total flavonoid and phenolic content, In vitro sun protecting activity and physicochemical parameters. The Total flavonoid and Phenolic content were found to be 42.07 mg QE/g and 57.03 ± 3.06 mg GAE/g respectively. While the SPF values were found to be 1.75,2.94,3.87 for the concentration 20 µg/ml, 30 µ g/ml and 40 µ g/ml respectively. From the study we can conclude that cream containing herbal extracts will enhance the sun protection property and it will significantly contribute to UV absorbing property of conventional herbal sunscreen formulations. It will provide the great advantage of avoiding the adverse and undesirable effects pf synthetic compounds.
