	abstract = {It has been observed that the leaves of some Zamia species undergo a kind of “reverse ripening”; that is, they change from their original brown color to green during development. We assumed that this strange color change was due to the change in carotenoid composition, so we followed the changes for several weeks. The detailed carotenoid composition and content at different stages of development of the leaves was determined with HPLC-DAD focusing on the changes in red and yellow carotenoids. The total and relative amounts of red and yellow carotenoids were determined simultaneously from one measurement from a saponified and/or unsaponified extract. At the beginning of development, the concentration of red carotenoids was higher than that of the yellow ones; it decreased drastically until 22 days and continued to decrease slowly until they completely disappeared. The concentration of yellow carotenoids decreased at the beginning as well, but after 22 days it started to increase. The amount of red carotenoids started to decrease when the leaflet stopped growing. Lutein is the main component in old leaflets, which is not a red carotenoid precursor. Red carotenoids can always be found in their esterified form in the leaves. These findings support the hypothesis that red and yellow carotenoid accumulation are independent and probably have different functions in the leaflet. The strange color change was explained based on the compartmentalization of red and yellow carotenoids and on the changing activity of the enzyme capsanthin–capsorubin synthase responsible for the synthesis of red carotenoids capsorubin and capsanthin.},

	abstract = {Currently, the antimicrobial activity of essential oils (EOs) is an outstanding research field due to antibiotic resistance of microorganisms. Thin-layer chromatography‒direct bioautography (TLC‒DB) is an effective, fast method to find components with antimicrobial activity in a mixture of plant compounds, e.g., in EOs. The volatility and hydrophobic characters of EOs require special experimental conditions, and disc diffusion assay is not appropriate to explore the antimicrobial activity of them. The aim of this study was to use “R” mutants, which are more sensitive to synthetic antimicrobial drugs, in DB to increase the sensitivity of this method. Our hypothesis was that these mutants show sensitivity to some EOs (thyme, clove, and peppermint) as well. The chemical composition of our tested EOs was measured with gas chromatography‒mass spectrometry (GC‒MS). The main compounds (39.8% thymol, 78.8% eugenol, and 50.4% menthol) of EOs showed notable antibacterial activity in TLC‒DB. Based on our results, we suggest to use Salmonella minnesota Re595 rough strain as test bacterium in bioautography, because it showed the highest sensitivity to the tested antibiotics (gentamicin and cephalexin) and EOs. Furthermore, this rough mutant could make TLC‒DB more faster, because only 4 h incubation time was enough to detect the inhibition zones of the active compounds used in this study.},
