Oznake: HILIC;dekstranska lestvica;retencijski mehanizem;entalpijsko-entropijska kompenzacija;dextran ladder;retention mechanism;enthalpy-entropy compensation;
Hydrophilic interaction liquid chromatography (HILIC) is widely used for the analysis of glycans and oligosaccharides, yet the molecular basis of retention remains incompletely understood. In this study, we investigated dextran ladders labelled with 2-aminobenzamide (2-AB) and Rapifluor-MS™ (Waters, ...

Discriminating cinnamon species and geographic origin using HPLC-UV and chemometrics
Jernej Markelj, Katja Kastelec, Matjaž Grčman, Drago Kočar
Izvirni znanstveni članek
Oznake: cinnamon species;liquid chromatography;biomarkers;chemometrics;classification;geographical origin;
The aim of this study was to evaluate biomarkers for the differentiation and classification of cinnamon species and geographical origin. A reverse phase high performance liquid chromatography method with UV-Vis detection was used to quantify the following biomarkers: coumarin, cinnamic acid, cinnama ...

Development of an analytical procedure for the quantification of artemisinin in encapsulated formulations
Ana Šijanec, Matjaž Grčman, Matevž Pompe, Drago Kočar
Izvirni znanstveni članek
Oznake: artemizinin;enkapsulacija;prehranska dopolnila;stabilnost;HPLC-UV/Vis;kontrola kakovosti;priprava vzorca;artemisinin;encapsulation;food supplements;stability;quality control;sample preparation;
Encapsulated formulations have emerged as a promising tool for increasing nutrient absorption in the food supplement and cosmetic industries. Although the theoretical amplification factors for improving the bioavailability of encapsulated formulations are very high for poorly soluble active compound ...

The glycosylation process plays a crucial role in the structural integrity and biological activity of glycoproteins, where glycans are attached to a protein backbone. There are many kinds of glycans, the most common being N-glycans, which can be arranged into three classes, that is, complex, hybrid, ...

Georadarska ocena prostorske razsežnosti koreninskega sistema oljke (Olea europaea L.)
Urška Blejec, Matjaž Glavan, Branko Mušič, Damijana Kastelec, Helena Grčman
Magistrsko delo
Oznake: koreninski sistem;struktura korenin;meritve lokacije korenin;zaznavanje korenin;prostorska razsežnost korenin;georadarska metoda;voda v tleh;
V magistrskem delu smo preverjali ustreznost uporabe georadarske metode za določanje razsežnosti koreninskega sistema oljke ob meritvi vode v tleh kot pokazatelja lokacije korenin. Lokacijo korenin smo določali posredno z meritvijo vode v tleh, z neinvazivno geofizikalno-georadarsko metodo (GP ...
