TI  - The investigation of fatty acids compositions of Jerusalem artichoke (Helianthus tuberosus) herbage harvested at different phenological stages
AB  - This study was aimed to determine fatty acid compositions of Jerusalem artichoke herbages (Helianthus tuberosus)at five different phenological stages. Jerusalem artichoke was harvested at early vegetative, vegetative, early flowering, full flowering,and early seed stages and its herbage samples were obtained. In the herbages, the saturated fatty acid (∑SFA), unsaturated fatty acid(∑UFA), polyunsaturated fatty acid (∑PUFA), monounsaturated fatty acid (MUFA), medium chain fatty acids (∑MCFA), long chainfatty acids (∑LCFA) and very long chain fatty acids (∑VLCFA) were analyzed. The linoleic acid (C18:2n 6c) concentrations ofherbages were changed from about 21 to 23% at different growing stages (P<0.05). The oleic acid (C18:2n 6t) concentrations of thisforage increased with plant growing (20 to 34% in total fatty acids) (P<0.001). The ∑PUFA, w-3, w-6, ∑MCFA and ∑VLCFAconcentrations of Jerusalem artichoke herbage were positively correlated with plant growing stage (from vegetation to after flowering)(P<0.05). The ∑MUFA, w-9 and ∑LCFA concentrations of this herbage were negatively correlated with plant growing stage of plant(P<0.05). As a result of the study, the ∑UFA, ∑MUFA and w-9 fatty acids compositions of Jerusalem artichoke herbage, harvested atearly flowering stage, were high than those of other plant growing stages. Besides, the Jerusalem artichoke herbage, harvested atflowering stage, was rich from ∑PUFA, w-3 and ∑VLCFA fatty acids. Therefore, Jerusalem artichoke herbage, harvested at earlyflowering and full flowering stages, has high functional properties for ruminants and other herbivorous.
