“…The identification is based on their chromatographic and spectroscopic properties, as well as the cochromatography of the corresponding standards. All the identified carotenoids were in free form as in previous reports (Rodriguez-Amaya, 1996;de Rosso et al, 2007), a peculiar fact due to the high content of oils of these fruits. Other oil-rich fruits, such as olives, have shown a similar profile without esterified carotenoids (Mínguez-Mosquera et al, 1992).…”

“…Generally, the palm fruits studied until now are rich in ß-carotene (Rodriguez-Amaya, 1996;de Rosso et al, 2007), as the ß, ß pathway domains (Figure 1) during carotenoid synthesis, as is the case in the oils obtained from buriti, pupunha and tucumã. The dominance of the ß, ß series in fruits is transferred to the respective oils in these varieties, as can be observed in Table 2, where the carotenoid profile is dominated by ß-carotene.…”

“…However, the oils extracted from palm fruits have only been characterized spectrophotometrically for their total carotenoid content (Mambrine et al, 1997, Ferreira et al, 1999Fihlo et al, 2013), and these have been considered as potential sources of carotenoids (Manorama et al, 1991;Rodriguez-Amaya, 1996). In fact, the enrichment of foods with natural sources of β-carotene, such as these palm oils, could be an alternative solution to preventing the hypo-vitaminosis A disorder in Brazilian population (Ambrosio et al, 2006).…”

SUMMARY:The oils obtained from native palm fruits are considered new sources of high added value phytochemicals, making it necessary to know the composition of the less studied species in order to evaluate their economic potential. The objective of this study is to identify and quantify the carotenoids in palm fruit oils from the Brazilian Amazon: bacaba (Oenocarpus bacaba), buriti (Mauritia flexuosa), inajá (Maximiliana maripa), pupunha (Bactris gasipaes) and tucumã (Astrocaryum vulgare), by means of liquid phase extraction and HPLC-UV-vis. analysis. The results showed an extremely variable carotenoid content, from 13 mg·kg −1 in bacaba oil to more than 1000 mg·kg −1 in the tucumã one. The oils obtained from buriti, pupunha and tucumã displayed high concentrations of ß-carotene, corresponding to fruits with the series ß, ß dominant metabolism. Upon analyzing the carotenoid profile in bacaba oil for the first time, an extraordinary dominance of the ß, ε pathway was observed, proving them to be oils with high lutein and α-carotene contents. Although the ß, ß pathway dominates in inajá oil, the exclusive and high lycopene content implies that LCY-E is barely active in these fruits, in contrast to what has been evidenced so far. It is therefore of the utmost importance to characterize these new potential sources of carotenoids.KEYWORDS: Astrocaryum vulgare; Bactris gasipaes; HPLC-carotenoids; Mauritia flexuosa; Maximiliana maripa; Oenocarpus vacaba; Palm oils RESUMEN: Composición de carotenoides en aceites obtenidos a partir de frutos de palma de la Amazonia Brasileña. Los aceites obtenidos a partir de frutos de palmeras nativas son considerados nuevas fuentes de fitoquímicos con alto valor añadido siendo necesario conocer la composición de las especies menos exploradas para evaluar su potencial económico. El objetivo de este estudio es identificar y cuantificar los carotenoides en aceites defrutos de palmeras provenientes de la Amazonia Brasileña: bacaba (Oenocarpus bacaba), buriti (Mauritia flexuosa), inajá (Maximiliana maripa), pupunha (Bactris gasipaes) y tucumã (Astrocaryum vulgare), mediante extracción líquido:líquido y análisis por HPLC-UV-vis. Los resultados mostraron un contenido de carotenoides muy variable, entre 13 mg·kg −1 en el aceite de bacaba y superior a 1000 mg·kg −1 en el aceite de tucumá. Los aceites procedentes de buriti, pupunha y tucumã presentaron altas concentraciones de ß-caroteno, correspondiendo a frutos con metabolismo dominante de la serie ß, ß. Al analizar por primera vez el perfil carotenoides del aceite de bacaba se observó una excepcional dominancia de la ruta ß, ε, y consecuentemente presenta un alto contenido en luteína y α-caroteno. Aunque en los aceites de inajá predomina la ruta ß, ß, el exclusivo y alto contenido de licopeno implica que LCY-E es muy poco activa en estos frutos, a diferencia de lo descrito hasta el momento. Resulta pues fundamental caracterizar estas nuevas potenciales fuentes de carotenoides.

“…From a nutritional point of view, b-carotene is considered to be the main provitamin A (Niizu, RodriguezAmaya, 2005;Moreira et al, 2005; Campos et al, 2003;Almeida-Muradian, Penteado, 2003;Rodriguez-Amaya, 1996).…”

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., ...
