Together with ten well known compds., the quinic acid deriv. chlorogenic acid, the nucleoside adenosine, two amino acids, tryptophan and phenylalanine, the anthraquinone derivs., aloemodin, aloemodin acetate and chyrosphanol 1-O-gentiobioside, the flavon C-glycosides, isovitexin, isoorientin and isoorientin 4'-O-beta -glucopyranoside, as well as two new acylated isoorientin derivs., 6''-O-(malonyl)-isoorientin and 6''-O-[(S)-3-hydroxy-3-methylglutaroyl]-isoorientin, were isolated from the water sol. part of the methanolic ext. of the fresh leaves of Asphodelus aestivus. All compds. were structurally identified by spectroscopic methods, including UV, MS, and NMR (1D and 2D) spectroscopy. Among the compds. isolated, chlorogenic acid and isoorientin were found to be the main compds. of the methanolic ext.
