Introduction: Plants, due to presence of secondary metabolites like flavonoids, phenols, have been used for various skin care purposes. The ethanolic extracts of different parts of various plants were screened for phytochemicals. Total phenols, total flavonoids, in vitro Sun Protection Factor (SPF) were determined and sunscreen cream was formulated and evaluated from the most potent plant extract. Method: Extraction was done by double maceration. The total phenol content was determined colorimetrically using Folin-Ciocalteu reagent and flavonoid content by aluminium chloride colorimetric method. In vitro SPF was determined by spectrophotometric analysis using Mansuer equation. Formulation was done by incorporating oil phase into aqueous phase. Results: Phytochemical analysis suggested the presence.. Read More»
