Study of the volatile fraction of distillates with added donkey thistle (Onopordum acanthium L.) extracts

ethanol extracts of donkey thistle (Onopordum acanthium L.) was conducted. The were added to the pure distillate from grapes Melnik-55 grapevine variety in amounts 20, 50, 80, 100, 200, 400 and 600 ml. remaining amount liter a distillate. A (without extracts) used as control. addition 50% extract Onopordum L. increased total volatile composition variants 1000:20 1000:50, comparison control sample. Higher levels esters higher alcohols found same variants. Incorporation 70% resulted final terpene content distillates. By increasing extract, reduction concentrations acetaldehyde ethyl acetate basic ester all distillates analyzed acetate, major 2-methyl-1-butanol, 3-methyl-1-butanol, 1-propanol 2-butanol. applying plant, methanol observed. prospect application L, especially 1000:50. This two showed aromatic compounds (beverage quality) slightly terpenes (biological value) compared other this group had proven lower (improved toxicological
