“…The antioxidant properties of açai have been previously described in the literature (Kuskoski et al, 2006;Kang et al, 2011;Gordon et al, 2012;Inácio et al, 2013). However, although incorporation of açai glycolic extracts into sunscreen emulsion did not increase SPF in vivo, this formulation may be effective as an antioxidant cosmetic product.…”

“…is a palm native to the Amazon. Its fruits are of economic importance in the Brazilian state of Pará and contain in addition to essential nutrients, anthocyanins, a class of polyphenols to which antioxidant properties have been attributed (Kuskoski et al, 2006;Kang et al, 2011;Gordon et al, 2012;Inácio et al, 2013). Anthocyanins are the predominant polyphenols and account for more than 90% of açai´s total polyphenolic contents (Pacheco-Palencia et al, 2009).…”

Euterpe oleracea Mart. is a palm tree popularly known as açai, which is primarily found in northern Brazil. The açai's fruits contain anthocyanins, a class of polyphenols to which antioxidant properties have been attributed. The aim of this work was to develop O/W sunscreens emulsions containing açai glycolic extract (AGE) and to evaluate both their physical stability and photoprotective efficacy. Emulsions containing AGE and sunscreens were formulated using different types and concentrations of polymeric surfactant (acrylates/C 10-30 alkyl acrylate crosspolymer and sodium polyacrylate). The influence of two rheology modifiers (polyacrylamide (and) C13-14/isoparaffin (and) Laureth-7 and Carbomer) on the stability was also investigated. Physical stability was evaluated by preliminary and accelerated studies. Emulsions with 1.0% sodium polyacrylate were stable and exhibited non-newtonian pseudoplastic behavior and thixotropy. Photoprotective efficacy was evaluated by in vivo Sun Protection Factor (SPF) and determination of Protection Factor of UVA (PF-UVA). When AGE was added to the sunscreen emulsion, no significant increase in the in vivo SPF value was observed. The emulsion containing AGE showed PF-UVA = 14.97, 1.69 of the SPF/PF-UVA ratio and a critical wavelength value of 378 nm, and may therefore be considered a sunscreen with UVA and UVB protection. Euterpe oleracea Mart. é uma palmeira popularmente conhecida como açaí, encontrada no norte do Brasil. O fruto do açaí apresenta em sua composição antocianinas, uma classe de polifenóis à qual é atribuída propriedade antioxidante. Os objetivos desse trabalho foram desenvolver emulsões fotoprotetoras O/A contendo extrato glicólico de açaí (AGE), avaliar a estabilidade física e avaliar a eficácia fotoprotetora. Emulsões contendo AGE e filtros solares foram formuladas utilizando diferentes tipos e concentrações de tensoativo polimérico (acrilates/C 10-30 alquil acrilato polímero cruzado e polilacrilato sódico). A influência de dois modificadores reológicos (poliacrilamida (e) C13-14/isoparafina (e) Laureth-7 e Carbomer) na estabilidade foi avaliada. A estabilidade física das emulsões foi avaliada por meio de estudos de estabilidade preliminar e acelerada. Emulsões com 1,0% poliacrilato sódico foram estáveis, exibiram comportamento não-newtoniano pseudoplástico e tixotrópico. A eficácia fotoprotetora foi avaliada pelo teste in vivo de Fator de Proteção Solar (FPS) e pela determinação do Fator de Proteção UVA (FP-UVA). Quando adicionado o AGE na emulsão contendo filtros solares, não se observou aumento significativo no valor do FPS. A emulsão contendo o AGE apresentou FP-UVA=14,97, a razão FPS/ FP-UVA = 1,69 e o comprimento de onda crítico igual a 378 nm, podendo ser considerado um protetor solar com proteção UVA e UVB.

“…), which was reported to be 28.5 ± 0.6 mg GAE/100 g (YAHIA; ORNELAS-PAZ, 2010). The phenolic content of the yellow mombin was smaller only than that of acerola (Malpighia emarginata) (580.1 mg GAE/100 g), camarinha (Gaylussacia brasiliensis) (492.87 mg GAE/100 g), and mango (544 mg GAE/100 g) (BRAMORSKI et al, 2011;KUSKOSKI et al, 2006).…”

“…According to Tiburski et al (2011), the yellow mombin pulp presented a total phenolic content of 260.21 ± 11.89 mg GAE/100 g, which was higher than that found in most fruit pulps consumed in Brazil. Tiburski et al (2011) found that açaí berry (Euterpe oleracea, Mart) had a phenolic content of 36.8 mg GAE/100 g, while guava had 83.1 mg GAE/100 g, strawberry 132.1 mg GAE/100 g, pineapple 21.7 mg GAE/100 g, soursop 84.3 mg GAE/100 g, and passion fruit 20.2 mg GAE/100 g (KUSKOSKI et al, 2006). In comparison with other exotic fruits, the yellow mombin had a higher total phenolic content than mamey (Pouteria sapota Jacq.…”

“…Acai, a fruit of the acai palm (Euterpe oleracea Mart. ), is an important native fruit in this sector (GARZÓN et al, 2017) due to its nutritional value (MENEZES; TORRES; SRUR, 2008), high nutrient contents, such as protein, lipids and minerals (NEVES et al, 2015), and high anthocyanin contents, which are phenolic substances with coloring and antioxidant properties (BORGES et al, 2016;GARZÓN et al, 2017;KUSKOSKI et al, 2006). These properties qualify the acai as a functional food (PORTINHO; ZIMMERMANN; BRUCK, 2012).…”
