Antioxidant activity and potential photoprotective from amazon native flora extracts

Formulation and Characterization of Novel Nanostructured Lipid Carriers with Photoprotective Properties Made from Carnauba Wax, Beeswax, Pumpkin Seed Oil, and UV Filters

“…The CI of F1 was 0.63, which less than 1 indicated the presence of synergistic effect between PSO with the Uvinul® A Plus B that showed a higher in vitro SPF value. According to literatures, the occurrence of phenolic compounds does contribute to the photoprotective effect (Afaq and Katiyar, ; Martins et al, ). From the result of in vitro antioxidant activities and in vitro photoprotective properties (Table ), sample F1 exhibited the highest value in both DPPH and ABTS radical scavenging activity, meanwhile exhibited the highest SPF value among three samples.…”

“…The presence of bioactive compound merges with the perspective of the sophistication of consumer markets and the concern to be healthy. It is noteworthy that the use of compounds with antioxidant activities can prevent or delay damage to genetic material or lipid peroxidation (Martins et al, ). Tocopherols are excellent lipophilic antioxidants and were found to have total amount of 80.65 mg/100 g PSO (Nyam et al, ), which can inhibit lipid peroxidation, transfer its hydrogen, and thereby reduce the free radicals (Bardaa et al, ).…”

Analysis of Brazilian Plant Extracts as Potential Source of Antioxidant Natural Products Using Bench-Top Assays

“…2 Recent studies described the screening of Brazilian plant extracts for the antioxidant activity, as was made with six plant extracts aiming their antioxidant and photoprotective activity, which showed that the extract from Dalbergia monetaria is a potentially source of new antioxidants to be used in photoprotective formulations. 3 The alcoholic extract from the rhizomes of Aristolochia cymbifera and the aqueous extracts of the leaves of Caesalpinia pyramidalis and Cocos nucifera were evaluated against micro-organisms related to oral diseases, as well as their antioxidant activity was assessed and showed to be more effective than those observed to Ziziphus joazeiro, a well known antibacterial traditional plant. 4 Amazon rain forest is the biggest in the world, as it is the richest in terms of biodiversity, both for plants and animals, 5 although much of it remains unknown from the pharmacological point-of-view.…”

Novas alternativas terapêuticas para prevenção do câncer labial com produtos à base de extratos naturais com potencial fotoprotetor: uma revisão de literatura

“…Portanto, para um protetor solar ser considerado eficaz em sua atividade fotoprotetora, ele depende da relação entre a absorção de energia, a concentração do extrato, o intervalo de absorção e o comprimento de onda em que ocorre a absorção máxima. Esse fato corrobora com os achados da pesquisa realizada por Martins et al 33 (2016), que observou que, das seis espécies de plantas estudadas, apenas uma apresentou efeito fotoprotetor, embora todas apresentassem potencial antioxidante.…”
