Component composition of low-molecular volatile organic compounds of Nuphar lutea (Nymphaeaceae) at the beginning of vegetation
Chromatography-mass spectrometric analysis of essential oil of growing in Russia Nuphar lutea (separately for blades and petioles) has been carried out for the first time. 139 low-molecular volatile organic compounds (LMVOCs) were found and 122 of them were identified. Among LMVOCs of yellow water-lily (floating leaves and petioles) fatty acids (66% and 19% respectively), alcohols (11 and 50%) and esters (in 10%) predominated. The most abundant components were hexadecanoic acid (48.75 and 10.44%) and manool (1.63 and 44.79%). It is shown that the composition of LMVOCs of floating leaves (92 components) and their petioles (103 components) are very different (only 55 common substances). Particular attention is paid to the discussion on LMVOCs with marked biological and ecological functions.
