“…Carotenoids, found in vegetable oils, have antioxidant and anti-carcinogenic properties (Anjo, 2004;Uenojo et al, 2007). According to Ambrósio et al (2006), β-carotene is a powerful antioxidant which protects against cardiovascular diseases once it has inhibited the oxidation process of low-density lipoproteins (LDL).…”

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.

“…Carotenoid levels usually remain constant in leaves until early senescence (Uenojo et al, 2007), however an increase during ripening can be seen, at which there is an intensification of the synthesis of this compound (John et al, 1970). Here, the higher content found is in accordance with the stage of production of older trees at the moment of collection.…”

Abstract. Annona squamosa L. has been recognized by having compounds with important in vitro biological activity against human disease or as insecticide. However, knowledge of the antiviral potential and micro molecules production of A. squamosa L. at different phenological stages is scarce. The secondary metabolites detection and biological activity from seeds and leaves in 4 and 14 years old trees from semi arid region were performed. Phytochemical identification was obtained by chemical bioprospection and histochemical localization in leaves and seeds'. Seeds acids content was analyzed by gas chromatography. Cytotoxic effect and antiviral activities against equine and suid herpesvirus were also performed. Results showed differences in the amount of flavonoids, carotenoids, and phenolic compounds between leaves and seeds and by stage of production. Carotenoids and phenolic compounds, especially tannins, were higher in older trees' leaves. Fat acids detected in seeds were oleic, linoleic arachidic, Cis-11-eicosenoic, elaidic and palmitoidic acids. Cytotoxicity was higher in hydrophobic than hydroalcoolic extracts. Broad spectrum antiviral activity was more marked for younger trees' aqueous extract. The high chemical adaptability of A. squamosa to semi arid environment was evident and the identification of A. squamosa secondary metabolites regarding the plant senescence may guide a better utilization of plant organs in order to obtain substances of pharmacological interest.

“…As reported by Uenojo et al (2007), carotenoid levels in fruit cells remain relatively constant until the onset of senescence, and two types of enzymes are responsible for the oxygenation and degradation of carotenoids: lipoxygenase derived from chloroplasts, which catalyze the conversion of unsaturated lipids into aroma compounds; and peroxidase, from mitochondria. β-carotene retention in the juice of the fruits of grafted plants in wild Passiflora reveals the benefit of maintaining their nutritional bioavailability.…”

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.
