“…Campos et al (2006) found no variation in the carotene content of vegetables sold in Viçosa, MG, between three seasons of the year (spring, summer and autumn), except for green peppers. However, in countries such as Brazil where differences in climate conditions are only observed between summer and winter, the carotenoid content of vegetables may vary between these two seasons.…”

This study investigated the a-and b-carotene content and provitamin A value of four leafy vegetables sold at local and street markets in Viçosa, MG, Brazil, in the spring and winter of 2002. Carotenoids were analyzed by high-performance liquid chromatography. a-Carotene was detected in all samples sold during spring, but was only present in a few samples of smooth and curly lettuce and kale in winter. b-Carotene was found in marked quantities in all leafy vegetables analyzed. Duncan's test (α = 5%) showed significantly higher a-carotene content in curly lettuce and vitamin A value in large-leaved watercress in the spring. Mean b-carotene content and vitamin A value were 7544, 8751, 2584, 2792, 8193, and 5338 mg/100 g and 666, 760, 227, 238, 698, and 460 mg RAE/100 g in large-leaved and hydroponic watercress, smooth and curly lettuce, kale and spinach, respectively. All leafy vegetables analyzed represent important sources of provitamin A and supply an important part of the daily requirements of children and adults.Uniterms: a-Carotene. b-Carotene. Leafy vegetables/analysis. Provitamin A.Investigou-se o conteúdo de a e b-caroteno e avaliou-se o valor pro-vitamínico A de quatro hortaliças folhosas comercializadas em mercados locais e feira-livre de Viçosa, MG durante a primavera e o inverno de 2002. Os carotenóides foram analisados por Cromatografia Líquida de Alta Eficiência (CLAE). O a-caroteno foi detectado em todas as amostras analisadas na primavera, porém no inverno, somente algumas amostras de alface crespa e lisa, e couve apresentaram tal carotenóide. O b-caroteno foi encontrado, em quantidades apreciáveis, em todas as hortaliças folhosas analisadas. O teste de Duncan (α=5%) detectou que o conteúdo de a-caroteno em alface crespa e o valor de vitamina A em agrião de folha larga foram estatisticamente superiores na primavera. Os teores médios de b-caroteno e de valor de vitamina A para agrião de folha larga e hidropônico, alface crespa e lisa, couve e espinafre foram: 7544; 8751; 2584; 2792; 8193; 5338 mg/100g e 666; 760; 227; 238; 698; 460 mg RAE/100g, respectivamente. Todas as hortaliças folhosas analisadas constituem importantes fontes de provitamina A e suprem grande parte das recomendações diárias de crianças e adultos.Unitermos: a-caroteno. b-caroteno. Hortaliças folhosas/análise. Pró-vitamina A. INTRODUCTIONDark green leafy vegetables are good sources of minerals and vitamins (Raju et al., 2007), and are important because they are rich in provitamin A carotenoids (Graebner et al., 2004;Zanutto, Jordão, Vannucchi, 2003). Since humans are unable to synthesize carotenoids, they exclusively depend on dietary intake as a source of these micronutrients (Barbosa-Filho et al., 2008). Carotenoids have raised continued interest because of studies demonstrating their role in the prevention of certain types of cancer, such as lung, breast, oral cavity, colon and rectal cancer (Barbosa-Filho et al., 2008;Melendez-Martinez, Vicario, Heredia, 2004;Silva, Naves, 2001;Fontana et al., 2000;Olson, 1999;Cozzi et al., ...

“…Regarding the levels of β-carotene, the fruits analyzed in this study were compared, as a reference, to carrots, which are known by presenting concentrations of this carotenoid. Campos et al (2006) concluded that, out of the seven vegetables studied, carrots had the highest levels of β-carotene, with an average of 5.18 mg.…”

Effect of two wild rootstocks of genus Passiflora L. on the content of antioxidants and fruit quality of yellow passion fruit

2016

AbstrAct:The nutritional importance of the fruit of passionfruit has prompted studies to assess its composition and antioxidant content and to evaluate it as a functional food in fresh fruit and concentrated juice markets. Currently, the use of wild species as rootstock has been recommended mainly for their positive effects such as tolerance to disease attack and maintenance of fruit quality of grafted cultivars.The aim of this study was to determine the effect of wild species of on the same species were used. Significant correlations were observed among the contents of β-carotene, ascorbic acid, luminosity values, chroma and hue angle. For the combination P. edulis/P. gibertti, the contents of β-carotene and ascorbic acid were highly correlated with luminosity, chroma and hue angle of fruit juice. A similar behavior was observed for the combination P. edulis/P. mucronata Lam. The content of β-carotene in the fruit showed no statistical differences (p < 0.05), indicating no significant rootstock effect on the variables evaluated.The results indicate a potential wild rootstock use for its positive effects on grafted plants while maintaining the commercial quality of the fruits of passionfruit crops.
