Carotenoids and carotenoid esters of orange- and yellow-fleshed mamey sapote ( Pouteria sapota (Jacq.) H.E. Moore & Stearn) fruit and their post-prandial absorption in humans
(2017-04)Although different genotypes of mamey sapote with distinct pulp colors are consumed in countries from Central to South America, in-depth knowledge on genotype-related differences of their carotenoid profile is lacking. ... -
Characterisation of acylated anthocyanins from red cabbage, purple sweet potato, and Tradescantia pallida leaves as natural food colourants by HPLC-DAD-ESI(+)-QTOF-MS/MS and ESI(+)-MSn analysis
(2023)Anthocyanins in red cabbage, sweet potato, and Tradescantia pallida leaves were characterised. A total of 18 non–, mono-, and diacylated cyanidins was identified in red cabbage by high performance liquid chromatography-diode ... -
Characterization of Mesocarp and Kernel Lipids from Jacq., [Kunth] Cortés, and Their Interspecific Hybrids
(2017)Morphological traits, total lipid contents, and fatty acid profiles were assessed in fruits of several accessions of Elaeis oleifera [Kunth] Cortes,́ Elaeis guineensis Jacq., and their interspecific hybrids. The latter ... -
Characterization of phenolic compounds in jocote (Spondias purpurea L.) peels by ultra high-performance liquid chromatography/electrospray ionization mass spectrometry
(2012-05)Phenolic acids and flavonol O-glycosides were extracted from the peels of jocote fruits (Spondias purpureaL.,Anacardiaceae) harvested in Costa Rica and characterized using ultra high-performance liquid chromatog-raphy ... -
Coffee (Coffea arabica L.) by-Products as a Source of Carotenoids and Phenolic Compounds—Evaluation of Varieties With Different Peel Color
(2020)Analysis of pulp and peels of Arabica coffee varieties with different external fruit color allowed the identification of 16 phenolic compounds using high-performance liquid chromatography with diode array detection and ... -
