The paper presents new records for 39 vascular plant species from eight Eurasian countries. Aniselytron treutleri Poaceae , Hackelochloa granularis Poaceae , Melica kozlovii Poaceae and Melica nutans Poaceae are reported from China; Dichondra micrantha Convolvulaceae from Hungary; Orobanche serbica Orobanchaceae and Viscum album subsp. austriacum Santalaceae from Italy; Petrorhagia prolifera Caryophyllaceae , Puccinellia schischkinii and Stipa pulcherrima Poaceae from Kyrgyzstan; Megadenia speluncarum Brassicaceae , Phelipanche lavandulacea Orobanchaceae , Solanum physalifolium Solanaceae , Thymus lenensis Lamiaceae from Russia; Rubus phoenicolasius Rosaceae from Slovakia; Atraphaxis karata…

Conversion of Organic Dyes into Pigments: Extraction of Flavonoids from Blackberries (Rubus ulmifolius) and Stabilization
2021
The blackberry’s color is composed mainly of natural dyes called anthocyanins. Their color is red–purple, and they can be used as a natural colorant. Anthocyanins are flavonoids, which are products of plants, and their colors range from orange and red to various shades of blue, purple and green, according to pH. In this study, the chemical composition of an extract obtained from blackberries was defined by LC-ESI/LTQOrbitrap/MS in positive and negative ionization mode. Furthermore, we investigated the adsorption process of blackberry extract using several inorganic fillers, such as metakaolin, silica, Lipari pumice, white pozzolan and alumina. The pigments exhibit different colors as a func…
Rubus aetnicus Cupani ex Weston and R. canescens DC. (Rosaceae): an analysis
2021
Beek (2016) argued that Rubus aetnicus Cupani ex Weston was the correct name of the taxon that was then called R. canescens DC., and which was previously known as R. tomentosus Borkh. Moreover, R. canescens was stated to be not identical with R. aetnicus, but rather a form of R. × collinus DC. Matzke-Hajek (2016) raised objections to both statements. Therefore, the aim of this study was to thoroughly analyse both names and support this analysis with field work at the type localities and by DNA data. Despite the correspondence at the investigated conservative DNA loci, the investigation showed that the two species are morphologically different and must be conceived as separate taxa. Accordin…
