Jaboticaba, a Brazilian jewel, source of antioxidant and wound healing promoter

Abstract

This study aims to evaluate properties as antioxidant activity, solar protection factor (SPF) and wound healing ability of jaboticaba peel's extract by in vitro methods. Jaboticaba peels were removed, dried, and then subjected to extraction method using ethanol. The extract was in vitro evaluated for preliminary studies about SPF, antioxidant activity and wound healing assay. Thereafter the extract was incorporated in an oil-in-water emulsion (phytocosmetic). The phytocosmetic was submitted to stability study and in vitro SPF evaluation. The extract's showed purple color with in vitro SPF of 24.86, stimulated keratinocytes migration after 9 h of exposition and presented antioxidant activity. The incorporation of the extract gave the phytocosmetic formulation a light pink shade with an in vitro SPF of 19.00. Under stress conditions, the formulation was stable, especially when stored in low temperatures. Jaboticaba peel extract promoted wound healing in vitro presenting SPF and antioxidant activity. Final phytocosmetic formulation was stable when stored protect from light and heat, indicating that Jaboticaba extract can be used to develop products to protect skin against aging and sun exposure.
