Namen diplomskega dela je bilo s pomočjo literature ugotoviti, kako so bioaktivne snovi v sadju in zelenjavi dostopne za naše telo. Ker je ta skupina snovi zelo obsežna in med seboj raznolika, sem si za boljšo preglednost izbrala šest najbolj poznanih bioaktivnih snovi. V prvem delu sem predstavila posamezne skupine z njihovimi strukturnimi formula...
Mendel je kot utemeljitelj sodobne genetike odkril povezavo med lastnostmi in njihovim prenosom na potomce. Kasneje so odkrili molekulo DNA, ki omogoča prenos dednih informacij. Tako so mnoge lastnosti lahko razložene s poznavanjem genskega ozadja. Določeni geni, kot so naprimer Rht geni, ki vplivajo na višino pšenice so človeštvu omogočili prehran...
Čemaž (Allium ursinum L.) je zelnata trajnica, ki jo botanično uvrščamo v družino lukovk (Alliaceae) in v rod lukov (Allium). V Sloveniji je samonikel prisoten skoraj na celotnem ozemlju države. Čemaž se že stoletja uporablja v tradicionalni medicini zaradi svojih zdravilnih učinkovin, danes pa je poleg uporabe v sodobni farmaciji razširjen tudi v ...

Zeaxanthin dipalmitate (3) and two zeaxanthin dipalmitate derivatives, including one new compound (1), were obtained from wolfberry [the fruit of Lycium barbarum L. (Solanaceae)]. Their structures were unambiguously elucidated by spectroscopic analyses. Compound 2 is isolated from the genus Lycium for the first time, and its 1D/2D NMR data are firs...
In this work, Raman spectroscopy and density functional theory (DFT) calculations have been used in order to understand the nature of the interaction between the carotenoid bixin and organic solvents with dielectric constant varying from ca. 2 (toluene) to ca. 47 (dimethyl sulfoxide). Raman shifts registered for the main carotenoid marker band, the...
Traditional extraction remains the method-of-choice for phytochemical analyses. However, the absence of an integrated analytical platform, focusing on customized, validated extraction steps, generates tendentious and non-reproducible data regarding the phytochemical profile. Such a platform would also support the exploration and exploitation of pla...
Amber (yellow), Laird&rsquo / s Large (red) and Mulligan (purple&ndash / red) cultivars of New Zealand tamarillo fruit were separated into pulp (endo- and mesocarp) and peel (exocarp), and analyzed by liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS) for carotenoids, &alpha / -tocopherol and ascorbic acid contents. Fresh Mulligan...
