“…Geraldi et al 8 evaluated the total anthocyanin content by the differential pH method in yogurt samples containing juçara pulp (E. edulis; 7.0 g/100 g juçara pulp), which revealed an average total anthocyanin value of 2.0 mg/100 g of expressed equivalent to C3G, a lower value than obtained by Ribeiro et al 17 and Costa et al, 18 who reported anthocyanin content in juçara pulp of 235.8 mg/100 g and 110.09 mg/100 g respectively. However, the evaluation method used was different between the work of Geraldi et al 8 and the studies performed by Ribeiro et al 17 and Costa et al 18 Barroso et al 19 determined the content of C3R and C3G. The content ranged from 4.25 ± 0.08 mg g −1 C3R for E. edulis, and for E. oleracea it was from 2.13 ± 0.12 mg g −1 and 2.68 ± 0.93 mg g −1 for C3R and C3G respectively.…”

Euterpe edulis is a plant native of Brazil and popularly known as Juçara. The aim of this study was to develop and validate an analytical method by HPLC of the Juçara crude extracts (JCE), and to evaluate dairy products containing free and microencapsulated extracts. The validated method of the JCE was performed, using cyanidin‐3‐O‐rutinoside (C3R), isolated and identified as major component from JCE, as reference: linearity was used 10 concentrations between 25 and 250 μg mL‐1 (R2=0.994); LOD and LOQ: 19.04 and 57.7 μg mL‐1, respectively; accuracy RSD%<5; recovery, 104.85 μg mL‐1, and robustness. Physicochemical analyses of the dairy product were evaluated by colour, pH, and concentration of anthocyanins by HPLC calculated as C3R over 21 days of storage. The pH remained stable until the end of the test. The colouring and the concentration of anthocyanins remained stable for nine days. It was isolated C3R, the HPLC method was developed and validated, and colour stability was not altered until nine days.This article is protected by copyright. All rights reserved.

“…As antocianinas são pigmentos presentes em vegetais, responsáveis pela coloração que variam do vermelho intenso ao violeta e azul, apresentando diversas funções para as plantas, atuando como antioxidantes, proteção contra os raios ultravioleta, mecanismo de defesa e função biológica. Além disso, quando presentes em alimentos atuam na prevenção do organismo contra ação dos radicais livres, causadores de inúmeras doenças (Formiga et al, 2016;Ribeiro et al, 2011).…”

O umbuzeiro e a cajazeira são espécies frutíferas nativas de caráter extrativista de ocorrência no Nordeste brasileiro, que desempenham importante fonte de renda para as populações nos locais onde ocorrem. Seus frutos apresentam características de qualidade que os fazem ser muito apreciados tanto para o consumo in natura como para a fabricação de sucos, doces, geleias e sorvetes. No entanto, são espécies frutíferas ameaçadas de extinção devido à exploração irracional nos locais onde ocorrem, carecendo de estudos que tenham por objetivo sua domesticação e desenvolvimento de tecnologias que viabilizem a instalação de pomares comerciais. Verifica-se que praticamente inexistem informações na literatura sobre os constituintes bioativos destas espécies, sendo parâmetros importantes de qualidade, pois contribuem para inserção destes no mercado frutícola como produto diferenciado. Desta forma, o trabalho teve como objetivo quantificar os teores de antocianinas, flavonoides, pectina total e pectina solúvel em frutos de S. tuberosa Arr. Câm. e S. mombin L. procedentes da vegetação nativa do Estado de Alagoas. Foram quantificados os teores de antocianinas, flavonoides, pectina solúvel e pectina total. O fruto de umbu apresentou maior teor de antocianinas totais com valor médio de 1,65 ± 0,47 mg.100g-1, sendo que o fruto de cajá apresentou maior conteúdo de flavonoide totais com teor médio de 9,50 ± 0,71 mg.100g-1. Com relação aos teores de substâncias pécticas o fruto de umbu apresentou maior rendimento médio de pectina solúvel e pectina total, com valores de 28,64 ± 2,47% e 26,26 ± 4,35%. Os frutos das duas espécies de fruteiras nativas de Alagoas analisados apresentam em sua composição substancial conteúdo de substâncias com propriedades funcionais, constituindo-se em uma fonte potencial de antioxidantes naturais para a dieta humana. Eles também apresentaram bons teores de pectina total e solúvel, indicando seu potencial tanto para o consumo in natura quanto para o processamento agroindustrial.

“…Similar data were observed by Bezerra et al (2019) in Cyperaceae extracts. The absence of these compounds in green (for leaves) and brown (for roots) extracts is justifiable because anthocyanins are pigments belonging to a subgroup of flavonoids that occur mainly in fruits, vegetables, and flowers, presenting a wide variety of colors from intense red to violet and blue (Patras et al, 2010;Petroni and Tonelli, 2011;Ribeiro et al, 2011;Bezerra et al, 2018).…”

The genus Cyperus is widely distributed worldwide and occurs in various regions of Brazil. Research has reported the allelopathic potential of species belonging to this genus. From this perspective, the present study analyzes the phytochemical profile and allelopathic effect of seven concentrations of the aqueous extracts of Cyperus distans L., Cyperus laxus Lam., and Cyperus rotundus L. The allelopathic potential was evaluated in triplicate from germination bioassays on seeds of two species, Lactuca sativa L. and Emilia fosbergii Nicolson. In addition, phytochemical analyses were performed to analyze possible allelochemicals present in aqueous extracts of three species by phytochemical screening and high-performance liquid chromatography (HPLC). The evaluated variables were: germination (G) and germination speed index (GSI). The data obtained were submitted to the F test, and regression analysis was performed to compare means. The results showed higher susceptibility of E. fosbergii to aqueous extracts of C. distans, C. laxus, and C. rotundus at all concentrations analyzed (0.94, 1.87, 3.75, 7.5, 15, and 30%). In turn, the germination rate of L. sativa seeds decreased only at the highest concentrations (between 15 and 30%) of the same extracts. This allelopathic potential may be directly associated with the biosynthetization of phenolic compounds by Cyperus spp., analyzed in this study by phytochemical prospecting and HPLC.
