Abstract

Pereskia aculeata, popularly known as ‘ora-pro-nobis’, has high nutrition rates, provides better wound curing and good antioxidant activities. Free radicals are the main causes of changes triggered by skin aging and antioxidants cause the inactivity of the formation of free radicals. That is the reason why they are used in cosmetics. Current analysis determines the antioxidant activity of a formulation with the extract of Pereskia aculeata in a cream and compares its activity with anti-age creams on the market. Commercial samples were obtained from dispensing pharmacies and Pereskia aculeata leaves were used for the preparation of the concentrated extract. With regard to the antioxidant activity determined by the free radical method DPPH, extract had EC50 of 684.76 µg/mL. With regard to the creams´ antioxidant activity, sample B was higher, featuring 87.6%. Pereskia aculeata cream had an antioxidant activity close to 75%, similar to analyzed commercial samples. The extract may be used as an antioxidant active principal in cosmetic formulations for the prevention of skin aging.
