Description
Summary:Investigated the change of lipids, fatty acids and flavonoids in the leaves of Amaranthus retroflexus depending on phenological phase plant. It was found that since the budding phase to the phase of fruiting, a decrease in the lipid content in the leaves of Amaranthus retroflexus, which may be due to the formation of buds, flowers and seeds. Revealed that the leaves of Amaranthus retroflexus contain 18 fatty acids (FA) of which 9 - saturated and 9 - unsaturated. The main unsaturated fatty acids in the test plants - linolenic acid (C18:3Δ6,9,12), and saturated - palmitic acid (C16:0). Recorded decrease in the amount of total, saturated and unsaturated fatty acids since vegetation phase to fruiting. The maximum content of the amount of total, saturated and unsaturated fatty acids was observed during the growing phase. It is shown that the percentage content of unsaturated fatty acids in the leaves was increased with decreasing temperature. It was found that the leaves of Amaranthus retroflexus, which grows in Central Yakutia, contains rutin. Revealed an increase the concentration of rutin with the growing phase before fructification. It is shown that in the leaves of Amaranthus retroflexus highest content of rutin accounted for the phase of flowering and fruiting. Изучено изменение липидов, жирных кислот и флавоноидов в листьях Amaranthus retroflexus в зависимости от фазы развития растений. Установлено, что начиная с фазы бутонизации до фазы плодоношения происходило снижение содержания липидов в листьях Amaranthus retroflexus, что может быть обусловлено образованием бутонов, цветков и плодов. Выявлено, что в листьях Amaranthus retroflexus содержится 18 жирных кислот (ЖК), из которых 9 – насыщенные и 9 – ненасыщенные. Основная ненасыщенная ЖК в исследуемом растении – линоленовая кислота (С18:3Δ6,9,12), а насыщенная – пальмитиновая кислота (C16:0). Зафиксировано снижение суммы общих, насыщенных и ненасыщенных ЖК начиная с фазы вегетации до плодоношения. Максимальное содержание суммы общих, насыщенных и ...
