Factors Affecting the Content of Ergosterol and Zearalenone in Selected Grass Species at the End of the Growing Season
Original language description
The objective of the study was to assess the safety of forage prepared from selected grass species by means of the analysis of ergosterol and zearalenone. Graminaceous plants studied at the end of their growing season were Festulolium, Dactylis glomerataand Arrhenatherum elatius. Other indicators assessed were the content of ergosterol and zearalenone during the autumn and the intensity of use of grassland in the summer season on the studied contents of metabolites. Grasslands were harvested either inOctober, November or December. The secondary metabolites were analyzed by means of high performance liquid chromatography. At the end of the growing season, the ergosterol content was the lowest in the Festulolium forage (110.04 mg kg-1), the highest contents were observed in the Dactylis glomerata and Arrhenatherum elatius forages (145.73 mg kg-1 and 139.55 mg kg-1, respectively). The safety of Festulolium was also corroborated by the low zearalenone content (0.357 mg kg-1). On the othe

Obsah sekundárních metabolitů u vybraných druhů trav na konci vegetačního období
Czech description
Cílem příspěvku je posoudit prostřednictvím obsahu ergosterolu a zearalenonu bezpečnost píce Festulolium, Dactylis glomerata a Arrhenatherum elatius na konci vegetačního období. Vyhodnoceny byly také změny obsahu ergosterolu a zearalenonu v průběhu podzimu a vliv intenzity využití v letním období na obsah sledovaných metabolitů. Sledované sekundární metabolity byly analyzovány prostřednictvím vysokorychlostní kapalinové chromatografie (HPLC). Obsah ergosterolu byl na konci vegetačního období nejnižší vpíci Festulolium (110,04 mg.kg-1). Naopak nejvyšší obsah ergosterolu byl zaznamenán v píci Dactylis glomerata (145,73 mg.kg-1) a Arrhenatherum elatius (139,55 mg.kg-1). Bezpečnost Festulolium potvrdil také nízký obsah zearalenonu (0,357 mg.kg-1). Naopakvysoký obsah ergosterolu u Arrhenatherum elatius doplňuje také vysoký obsah zearalenonu (1,554 mg.kg-1). Píce Dactylis glomerata vykazuje koncem vegetačního období sice srovnatelný obsah ergosterolu jako píce Arrhenatherum elatius, ale ob
