Chemical constituents from Elegia tectorum and their chemophenetics importance

The phytochemical analysis of Elegia tectorum (L.f.) Moline and H.P.Linder led to the isolation of nine chemical constituents, categorized into one fatty acid, one phytosterol, one chromane derivative, three phenolic derivatives, and three flavonoid glycosides. The structure elucidation of the isolated compounds was achieved on the basis of NMR spectroscopy. The presence of flavonol glycosides (syringetin and laricitrin derivatives) in the investigated Elegia species is in line with previous findings on the genus Elegia. The chemical composition of E. tectorum was substantially supplemented. Importantly, the chemophenetics importance of isolated compounds has been discussed.
