Abstract

The objective of this work was to evaluate the UVA and UVB photoprotective effect and the antioxidant activity of dermatological cream developed with umbu-cajá (Spondias sp) extracts. The antioxidant activity of the cream was evaluated by the 1,1-diphenyl-2-picrylhydrazine (DPPH) radical inhibition method in triplicate, the dilutions were evaluated by spectrophotometer, with the absorbance values ​​determined at 517 nm. The evaluation of UVB and UVB photoprotective capacity was performed according to Mansur method and determining the UVA / UVB ratio and the critical wavelength. The developed cream showed antioxidant activity with inhibition close to 80% at 10 mg.mL-1 dilution. The spectrophotometer scan showed that the inputs and the cream can absorb ultraviolet light from 290 to 400 nm. The cream with umbu-cajá extract studied had antioxidant and photoprotective properties UVA / UVB and can be used as anti-aging cosmetic
