The fatty acid comparative essay of high aquatic plants: Typha latifolia L., Ceratophyllum demersum L. and Veronica anagallis-aquatica L. from water bodies of Baikalian region was carried out. For the first time this biochemical parameter of water form V. anagallis-aquatica was compared with that of coastal-water T. latifolia and submerged C. demersum. The fifteen individual molecules of fatty acids with a chain length from 12 to 22 carbon atoms have been identified by the method of gas liquid chromatography – mass spectrometry. The fatty acid composition of investigated species was different. Among the fatty acids saturated and unsaturated molecules was found, the most distributed fatty acids was saturated palmitic (С16:0), steric (С18:0) and unsaturated linoleic (С18:2 w6), α-linolenic (С18:3 w3). In total, the C16 and C18 acids in studied species accounted for 98%. Differences in the composition of fatty acids of the studied species are discussed from the standpoint of the characteristics of fatty acid metabolism depending on the habitat of plants and are considered as one of the mechanisms of their adaptation to late vegetation. Studies of the fatty acid composition of aquatic organisms contribute to the overall strategy of plant adaptation to changing environmental conditions and are important for the ecological and biochemical monitoring of the ecological status of water bodies.
