NEW FLAVONOL GLYCOSIDE FROM GUIBOURTIA EHIE (FABACEAE)
AbstractGuibourtia ehie (A. Chev.) J. Leonard is a medicinal plant widely used in the Ivorian traditional medicine against stomach ulcers, sexual infections, diabetes, hypertension and microbial infections, particularly those caused by amoeba and fungi. Furthermore, this plant is widely known for its commercial interest due to economic value of its wood. Biological and phytochemical investigations also confirmed local medicinal uses of the plant and showed a various chemical composition including numerous polyphenols. In this article, we reported the results of leaves studies of Guibourtia ehie, harvested in Côte d’Ivoire, which resulted in the isolation of a new flavonol, 8-isopentenylkaempferol-7-O–β-D-(2’’’-O-galloyl) glucopyranoside (1), that we named 2’’-O-Galloyl-epimedoside C, along with two phenolic known compounds, orcinol (2) and methyl orsellinate (3). The structures of compounds where elucidated by spectroscopic data including HR-ESIMS, UV, NMR 1D (1H and 13C) and NMR 2D (COSY, HSQC and HMBC). These compounds were isolated for the first time from Guibourtia ehie (A. Chev.) J. Leonard.
