Avaliação da atividade fotoprotetora da Schinopsis brasilienses Engler

Abstract

“Sunscreen activity evaluation of Schinopsis Brasiliensis Engler”. The photoprotective are a class of products capable of absorbing, reflecting or slow down the ultraviolet radiation, in order to avoid the dangers, to protect the skin from exposure to sunlight. Since the flavonoids are seen as an important factor of protection against ultraviolet radiation , some studies focus on the photoprotective avaliation that some plants, composed of flavonoids, may present. So, this work had an objective to evaluate the photoprotective activity of the extract from the leaves from Schinopsis brasiliensis. So, Through the vitro's test by ultraviolet spectrophotometry, where the analyzes were made in the crude extract and extract with filter SPF 30. The literature describe the presence of flavonoids in the leaves of Schinopsis brasiliensis, so the results were promising, because they showed that the leave showed a biggest absorption than the sunscreen already has.
