The aim of study was to investigate photoabsorptive property of extracts of the leaves of Pongamia pinnata(L.) Fabaceae, in the ultraviolet region (200–400 nm). The leaves powder of plant were extracted in Soxhlet apparatus using solvent ethanol. The extracts was concentrated by evaporation of the solvent and dried to get extracts. Then, 10 mg of the extracts was dissolved in the solvent using ethanol and their absorption spectra were measured using UV–visible spectrophotometer. Different concentrations of the extracts 5, 10, 15,20 and 25 mg/100 ml was read at their respective wavelength (λmax) of maximum absorption. The ethanol extract were found to be most effective in the UVB region and moderately effective in the UVC region and minor effective in the UVA region. The extracts of the leaves of the Pongam Tree‟ under study showed exact good absorbance throughout the UVC. The P. pinnata extracts be used for formulation of highly effective sunscreen preparations such as cream, lotion, as it will enhance effectively contribute to the UV along with the greatest use of avoiding the adverse and toxic effects of synthetic sunscreen compounds which having absorbing properties of a conventional sunscreen. It definitely useful in broadening the UV protection ability of the sunscreen which protect our skin from various skin related disease.

Keywords: Pongamia pinnata, phytochemical test, ethanoic extraction, antisolar, UV region (200–400 nm).
