Item type:Publication, NMR Profiling of North Macedonian and Bulgarian Honeys for Detection of Botanical and Geographical Origin(MDPI AG, 2020-10-14); <jats:p>Bulgaria and North Macedonia have a long history of the production and use of honey; however, there is an obvious lack of systematic and in-depth research on honey from both countries. The oak honeydew honey is of particular interest, as it is highly valued by consumers because of its health benefits. The aim of this study was to characterize honeydew and floral honeys from Bulgaria and North Macedonia based on their NMR profiles. The 1D and 2D 1H and 13C-NMR spectra were measured of 16 North Macedonian and 22 Bulgarian honey samples. A total of 25 individual substances were identified, including quinovose, which was found for the first time in honey. Chemometric methods (PCA—principal component analysis, PLS-DA—partial least squares discriminant analysis, ANOVA—analysis of variance) were used to detect similarities and differences between samples, as well as to determine their botanical and geographical origin. Semiquantitative data on individual sugars and some other constituents were obtained, which allowed for the reliable classification of honey samples by botanical and geographical origin, based on chemometric approaches. The results enabled us to distinguish oak honeydew honey from other honey types, and to determine the country of origin. NMR was a rapid and convenient method, avoiding the need for other more time-consuming analytical techniques.</jats:p> - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Extraction, Distribution and Diversity of Phenolic Compounds in Most Widespread <i>Boraginaceae</i> Species from Macedonia(Wiley, 2023-04-25); ; A systematic study of extraction efficiency of polyphenolic compounds from the most widespread Boraginaceae species was carried out. The optimal extraction was achieved with 50% (V/V) methanol for phenolic acids and flavonoids, 0.2 % (V/V) HCl in 50 % (V/V) methanol for anthocyanins and pure water for flavan-3-ols. The distribution and diversity of polyphenolic compounds in plant material obtained from wild-growing Anchusa officinalis, Cynoglossum creticum Mill., Echium vulgare, Echium italicum, and Onosma heterophylla Griseb. species from Macedonia was also assessed. These widespread Boraginaceae species contain phenolic acid derivatives, flavonoids, flavan-3-ols and anthocyanins and in total 31 of them were identified, from which 22 were first identified in the representative species, and 6,8-di-C-glucosides of apigenin and luteolin were identified for the first time in Boraginaceae. The profiles of polyphenolic compounds for each sample were obtained and their phytochemical profile established. The potential for further bioactivity studies of Anchusa officinalis and Cynoglossum creticum containing up to 24577.05 μg/g and 14304.15 μg/g of total polyphenols were assumed to be highest, followed by Echium vulgare (from 6382.61 to 14114.33 μg/g), Onosma heterophylla (9463.97 μg/g) and Echium (4108.14 μg/g). - Some of the metrics are blocked by yourconsent settings
