Maize (Zea mays) cell cultures were used for the production of zearalenone-4-β-D-glucopyranoside as standard compound. Wheat samples were extracted with acetonitrile: water, applied to a florisil column and eluted with methanol:ethyl acetate. For determination and quantification of zearalenone-4-β-D-glucopyranoside and zearalenone a LC-MS method was developed. A concentration of 10 μg/kg zearalenone-4-β-D-glucopyranoside...
Due to infections with moulds already in the vineyards, the formation of mycotoxins is possible under certain circumstances during the process of red wine making. At this, metabolites ofPenicillium spp. are of major importance, as this species are to be found frequently on grapes.
