“…Rufino et al (2010) sugeriram uma classificação dos teores de fenóis totais como baixo (<100 mg EAG 100 g -1 ), médio (100-500 mg EAG 100 g -1 ) e alto (>500 mg EAG 100 g -1 ) na matéria fresca; dessa forma, a guavira pode ser considerada como fruto de médio teor de fenóis totais.…”

“…Perspectivas promissoras para exploração de frutos tropicais não tradicionais se devem aos níveis consideráveis de vitamina C, antocianinas, carotenoides e compostos fenólicos, além da capacidade antioxidante destes frutos (RUFINO et al, 2010). Muita atenção tem sido focada para a atividade antioxidante total presente em frutas e hortaliças, devido aos diversos constituintes presentes que possuem propriedades de reduzir o nível do estresse oxidativo (HASSIMOTO et al, 2005), e consequentemente diminuir o risco de diversas doenças cardivasculares, neurodegenerativas e câncer (HALLIWELL, 2007;KAUR;KAPOOR, 2002).…”

RESUMO -Este trabalho foi realizado com o objetivo de avaliar a conservação pós-colheita de guavira (Campomanesia sp.), em função da utilização de 1-MCP e de atmosfera modificada passiva, além do armazenamento à temperatura ambiente e a 11°C. Os frutos foram colhidos no ponto de maturidade fisiológica, subdivididos em parcelas e submetidos à aplicação de 1-Metilciclopropeno (1-MCP) (700 ηL.L -1 /12horas) e à atmosfera modificada passiva por meio do uso de embalagem plástica. Foram realizadas análises de perda de massa, sólidos solúveis, acidez titulável, vitamina C, fenóis totais, atividade antioxidante e aparência geral dos frutos. O uso de 1-MCP não reduziu a perda de massa dos frutos, tanto em armazenamento ambiente quanto refrigerado, o que foi verificado com o uso da atmosfera modificada passiva. O armazenamento refrigerado reduziu a perda de massa dos frutos e prolongou a vida útil destes com manutenção dos teores de vitamina C, fenóis totais e atividade antioxidante. Os teores finais de sólidos solúveis e vitamina C dos frutos não apresentaram interferência significativa em relação aos tratamentos utilizados, e os valores de acidez titulável aumentaram ao final do período de armazenamento, com exceção dos frutos tratados com 1-MCP associado com atmosfera modificada e armazenados em ambiente. O uso de 1-MCP e de atmosfera modificada passiva prolongaram a vida útil dos frutos tanto em armazenamento ambiente, quanto refrigerado, com melhor aparência geral dos frutos, principalmente quando associados. Termos para indexação: atmosfera modificada, compostos bioativos, armazenamento refrigerado, 1-MCP. POST-HARVEST CONSERVATION OF GUAVIRA (Campomanesia sp.)ABSTRACT -This study aimed to evaluate the postharvest conservation of guavira (Campomanesia sp.), depending on the use of 1-MCP and modified atmosphere, as well as storage at room temperature and at 11°C. The fruits were harvested at physiological maturity, divided into portions and treated with 1-methylcyclopropene (1-MCP) (700 ηL.L -1 for 12 hours) and modified atmosphere, with plastic packaging. The fruits were submitted to the analysis of weight loss, soluble solids, titratable acidity, vitamin C, total phenols and antioxidant activity and general appearance. The use of 1-MCP did not reduce the fruit weight loss in both ambient and cold storage, which was verified using the modified atmosphere. The cold storage reduced the mass loss of the fruits and extended the shelf life maintaining the levels of vitamin C, total phenolics and antioxidant activity contents. The final concentration of soluble solids and vitamin C of the fruits showed no significant interference in relation to treatments. The titratable acidity values increased during the storage period, with the exception of fruits treated with 1-MCP associated with modified atmosphere and stored in room temperature. The use of 1-MCP and modified atmosphere extended the shelf life of fruits both in storage environment and cold, with a better overall appearance of the fruit, especially when combined.

“…The focus of antioxidant studies in the Myrtaceae family from Brazil has been on edible fruits (Marin et al, 2008;Rufino et al, 2009Rufino et al, , 2010Pereira et al, 2012) with few reports on leaves (Coutinho et al, 2008;Salvador et al, 2011). Thus, our results contribute valuable knowledge about the bioactive properties of native Myrtaceae species.…”

Antioxidant activity and phenolic content of leaf infusions of Myrtaceae species from Cerrado (Brazilian Savanna)

There is considerable interest in identifying new antioxidants from plant materials. Several studies have emphasized the antioxidant activity of species belonging to the Myrtaceae family. However, there are few reports on these species from the Cerrado (Brazilian savanna). In this study, the antioxidant activity and phenolic content of 12 native Myrtaceae species from the Cerrado were evaluated (Blepharocalyx salicifolius, Eugenia bimarginata, Eugenia dysenterica, Eugenia klotzschiana, Hexachlamys edulis, Myrcia bella, Myrcia lingua, Myrcia splendens, Myrcia tomentosa, Psidium australe, Psidium cinereum, and Psidium laruotteanum). Antioxidant potential was assessed using the antioxidant activity index (AAI) by the DPPH method and total phenolic content (TPC) by the Folin-Ciocalteu assay. There was a high correlation between TPC and AAI values. Psidium laruotteanum showed the highest TPC (576.56 mg GAE/g extract) and was the most potent antioxidant (AAI = 7.97, IC 50 = 3.86 µg·mL −1 ), with activity close to that of pure quercetin (IC 50 = 2.99 µg·mL −1 ). The extracts of nine species showed IC 50 of 6.24-8.75 µg·mL −1 . Most species showed TPC and AAI values similar to or higher than those for Camellia sinensis, a commonly consumed tea with strong antioxidant properties. The results reveal that the analyzed Myrtaceae species from the Cerrado possess high phenolic contents and antioxidant activities. Thus, they are a potential source of new natural antioxidants.

“…The results found in the present study are similar to those reported by Cheel et al (2007) in strawberries and by Jiao and Wang (2000) in blackberries. Rufino et al (2010) analyzed the correlation between the phenolic compounds and the total antioxidant activity of 18 tropical fruits by the ABTS method, and they found positive and significant correlations (0.92). Thaipong et al (2006) evaluated the antioxidant activity of methanolic extracts of guava by the ABTS and DPPH assays and obtained a significant correlation between the two methods.…”

Over the last decade a considerable increase in the number of studies addressing the use of antioxidants from natural sources has led to the identification and understanding of the potential mechanisms of biologically active components. This results from the fact that they can be used to replace synthetic antioxidants commonly used in food. Murtilla (Ugni molinae Turcz) is a native berry grown in Chile, and in the present study, the phenolic composition and antioxidant activity of its fruits were studied. Hydroalcoholic extracts of dehydrated fruits from two genotypes of murtilla (Ugni molinae Turcz.) were produced. Extracts of wild murtilla and 14-4 genotype fruits had 19.35 and 40.28mg GAE/g for Total Phenolic Compounds, 76.48, and 134.35μmol TEAC/g for DPPH, and 157.04 and 293.99 μmol TEAC/g for ABTS, respectively. Components such as quercetin, epicatechin, and gallic, benzoic and hydrocaffeic acids were identified by CG/MS analysis. All of them showed antioxidant activity. Therefore, it is possible to say that the hydroalcoholic extracts of murtilla have antioxidant potential to be used in lipidic food.
