Sažetak
Volatile fractions of evergreen candytuft, Iberis sempervirens (Brassicaceae), were isolated by simultaneous hydrodistillation-extraction from fresh plant material prior and after autolysis and from dried plant material and were then analyzed using GC and GC-MS. Isothiocyanates, nitriles, aliphatic alcohols, carbonyls, fatty acids, hydrocarbons, terpene compounds, C13-norisoprenoids and phenylpropane derivatives were identified – thirty-nine components in all. Major components of all samples were: 3-butenyl isothiocyanate (17.4–63.3 %), 5-methylthiopentanonitrile (2.2–9.5 %), 4-methylthiobutanonitrile (4.8–6.9 %), allyl isothiocyanate (4.0–6.6 %), 4-methylthiobutyl isothiocyanate (2.9–6.2 %) and 3-methylthiopropyl isothiocyanate (1.3–3.4 %). Oil isolated after autolysis is more complex than the other two oils. It is composed of a large number of compounds. Some of them are identified as O-aglycones such as eugenol, (Z)-3-hexene-1-ol and 1H-indole. O-glycosides of volatile compounds were isolated from fresh plant material and purified by selective extraction and column chromatography. After hydrolysis with b-glucosidase, the liberated volatile aglycones were also analyzed by GC and GC-MS. Nineteen aglycones were identified. The main aglycones identified were: eugenol (15.2 %), 2-phenylethanol (12.9 %), 2-hydroxy-b-ionone (10.6 %), 2-tert-butyl-5-methylphenol (9.2 %) and methyl-2,5-dihydroxybenzoate (4.5 %).
