This research aims to evaluate the antioxidant activity and sun protection factor of shells Ananas comosus (L.) Merrill cv. Smooth Cayenne and Ananas comosus (L.) Merrill cv. MDII identified in the Herbarium Truxillense (HUT), where they were assigned codes 58489 and 58490 respectively. The lyophilized cascara extracted with ethanol 96 ° G.L then concentrated and lyophilized.; obtaining the freeze-dried extract of the peel. Phenolic compounds were quantified by the Folin-Ciocalteu, and were expressed as gallic acid equivalents (EAG), whose values are 11 mg EAG / g and 12 mg EAG / g for the "white pineapple" and "yellow pineapple" respectively. The antioxidant activity was determined by the method of 2,2-diphenyl-1-picrylhydrazyl (DPPH) and as expressed as mean inhibitory concentration (IC50) whose values obtained ranged from 0,012 ± 0,75311 mg EAG / mL for white pineapple and of 0,8091...
