Abstract: | GC, GC/MS and NMR analyses of Scilla bifolia washings allowed for the identification of thirty-six long-chain compounds belonging to six homologous series (five of which are from the class of resorcinols, a group of biologically important phenols): 1-alkyl-3,5-dimethoxybenzenes, 5-alkyl-3-methoxy-2-methylphenols, 3-alkyl-5-methoxyphenols, 5-alkyl-2-methylresorcinols (five compounds from each of the series); 5-alkylresorcinols (six compounds) and 1,3-alkanediols (ten compounds). Many of these compounds rarely occur in Nature. Retention indices of these compounds, as well as indices of the corresponding trimethylsilyl derivatives, were reported, some of them for the first time. The exact regiochemistry was unambiguously determined by two-dimensional NMR experiments; in some cases, the complete NMR assignment was augmented by computer spin-simulation of 1H-NMR spectra. |
