Abstract
Diplomová práce se zabývá studiem terpenických látek obsažených v rostlinách máty. Terpenické látky jsou těkavé nízkomolekulární sloučeniny složené z několika isoprenových jednotek, které dávají rostlinám jejich typickou vůni a vyznačují se baktericidními a insekticidními účinky. Díky těmto účinkům je možné jejich využití jako botanické pesticidy, které nejsou toxické a nedochází ke vzniku rezistentních organismů. Každá rostlina však obsahuje velmi malé množství těchto látek, a proto se jejich množství zvyšuje za pomoci elicitorů. Elicitory aktivují v rostlině obranné mechanismy vedoucí ke zvýšené odolnosti a produkci sekundárních metabolitů. K identifikaci a kvantifikaci analytů byla použita metoda plynové chromatografie ve spojení s hmotnostní spektrometrií.
Diploma thesis is focused on study of compounds of terpenic nature in mint plants. Terpenic compounds are volatile hydrocarbons formed by several isoprenoid units with low molecular weight which cause the typical smell of plants. Presence of these compounds cause that plants seem to be fungicidal, bactericidal and insecticidal. Due to these properties, they can be used as botanical pesticides which are not toxic and no resistant organisms occur. Each plant contains relatively low concentrations of these compounds and therefore elicitors must be used for the increasing of terpenes amount. Elicitors activate defensive mechanisms in the plant leading to higher defense abilities and production of secondary metabolites. The identification and quantification of analytes was determined by gas chromatography in connection with mass spectrometry.
