The major and minor carotenoids from six fruits, buriti (Mauritia vinifera), mamey (Mammea americana), marimari (Geoffrola striata), peach palm (Bactrys gasipaes), physalis (Physalis angulata), tucuma (Astrocaryum aculeatum), all native to the Amazonia region, were determined by high-performance liquid chromatography−photodiode array detector−mass spectrometry detector (HPLC-PDA-MS/MS), fulfilling recommended criteria for identification. A total of 60 different separated on a C30 column,...

Fruits from the Atlantic Forest have received increasing interest because they contain high levels of bioactive compounds with notable functional properties. The composition carotenoids and phenolic fruits found in (jussara, uvaia, araça, grumixama) was determined by high-performance liquid chromatography coupled to diode array mass spectrometry detectors. Uvaia showed highest (1306.6 μg/100 g fresh matter (f.m.)). Gallic acid major compound araça (12.2 mg GAE/100 f.m.) uvaia (27.5 f.m.). In...

The carotenoid composition of mangoes produced in Brazil was determined by HPLC to appraise the effects some influencing factors. Total rose from 12.3 38.0 µg/g cultivar Keitt and 17.0 51.2 Tommy Atkins mature-green ripe stage. Ripening alterations occurred principally major carotenoids, violaxanthin beta-carotene. In mangoes, all-trans-beta-carotene, all-trans-violaxanthin, 9-cis-violaxanthin (location cis double bond tentative) increased 1.7, 5.4, 1.7 fruits 6.7, 18.0, 7.2 µg/g,...

The composition of carotenoids and phenolic compounds from jambolão fruits (Syzygium cumini) was determined by HPLC-DAD-MS/MS. Two main were found in the fruits, all-trans-lutein (43.7%) all-trans-β-carotene (25.4%). anthocyanin characterised presence 3,5-diglucosides five out six aglycones commonly foods. This pattern also observed for other flavonoids, since diglucosides dihydromyricetin, methyl-dihydromyricetin dimethyl-dihydromyricetin, along with myricetin glucoside a galloyl-glucose...

Anthocyanins and carotenoids are natural pigments responsible for the color of vegetables fruits, they also bioactive compounds, both demonstrating important biological, therapeutic, preventative properties. Considering biodiversity edible high performance liquid chromatography coupled to photodiode array mass spectrometry detectors (HPLC–PDA–MS) was used establish composition anthocyanins from dovyalis tamarillo fruits. Ten 26 were found in dovyalis, whereas showed 3 17 carotenoids. Higher...

Ripening affects the quality and nutritional contents of fleshy fruits, papayas are climacteric fruits very susceptible to postharvest losses due fast softening caused by ethylene. This paper reports changes in respiration, ethylene production, pulp color firmness, along with soluble sugars major carotenoids, during ripening 'Golden' papaya, an important Brazilian cultivar that has been exported North American European markets. The results obtained for nontreated ethylene- or 1-MCP-treated...

Carotenoid intake has been associated with the decrease of incidence some chronic diseases by minimizing in vivo oxidative damages induced reactive oxygen (ROS) and nitrogen species (RNS). The carotenoids are well-known singlet quenchers; however, their capacity to scavenge other species, such as peroxyl radical (ROO•), hydroxyl (HO•), hypochlorous acid (HOCl) anion peroxynitrite (ONOO−), still needs be more extensively studied, especially using membrane-mimicking systems, liposomes....

The composition of carotenoids and phenolic compounds from mana-cubiu (Solanum sessiliflorum), a fruit native to Amazonia, was determined by high-performance liquid chromatography coupled diode array mass spectrometry detectors (HPLC-DAD-MS(n)). antioxidant capacities the hydrophilic carotenoid extracts against some reactive oxygen (ROO(•), H(2)O(2), HOCl, HO(•)) nitrogen (ONOO(-)) species were also determined. Seventeen three found in mana-cubiu. major (all-E)-β-carotene (7.15 μg/g dry...

The consensus INFOGEST<italic>in vitro</italic>digestion method was adapted for carotenoids. systematic identification of carotenoid esters before and after<italic>in is presented the first time.

Large segments of the Brazilian population still suffer from malnutrition and diet-related illnesses. In contrast, many native fruits have biodiversity are underexploited sources bioactive compounds unknown to consumers. The phytochemical composition nine underexplored was determined. Carotenoids anthocyanins were identified quantified by high performance liquid chromatography-photodiode array-tandem mass spectrometry (HPLC-PDA-MS/MS), phenolic iridoids flow injection...

Sixteen carotenoids were isolated from the flesh of Brazilian red guavas (Psidium guajava L.). Their structures established by means UV−visible, 400 and 500 MHz 1H NMR, 120 125 13C mass, circular dichroism spectra. The identified as phytofluene, (all-E)-, (9Z)-, (13Z)-, (15Z)-β-carotene, (all-E)-γ-carotene, (15Z)-lycopene, (all-E,3R)-β-cryptoxanthin, (all-E,3R)-rubixanthin, (all-E,3S,5R,8S)-cryptoflavin, (all-E,3R,3'R,6'R)-lutein, (all-E,3S,5R,6R,3'S,5'R,8'R)-,...

Camu-camu [Myrciaria dubia (HBK) McVaugh] is a small fruit native to the Amazonian rain forest. Its anthocyanin profile has now been investigated for first time. Fruits from two different regions of São Paulo state, Brazil, were analyzed. The major anthocyanins isolated by high-speed countercurrent chromatography. HPLC−PDA, HPLC−MS/MS, and 1H NMR used confirm identity main camu-camu. Cyanidin-3-glucoside was identified as pigment in fruits both regions, representing 89.5% produced Iguape...
