Publication date: October 2019Source: Biochemical Systematics and Ecology, Volume 86Author(s): Habiba Laraoui, Hamada Haba, Christophe Long, Mohammed BenkhaledAbstractThe phytochemical study of ethyl acetate and n-butanol extracts of Fumana montana Pomel yielded a new flavanone sulfonate named naringenin-8-sulfonate (1), in addition to nine known compounds including two flavonols; tellimoside (2) and isoquercetrin (3), two flavanols; (−)-gallocatechin (4) and (−)-epigallocatechin (5), one benzophenone glucoside; iriflophenone-2-O-β-glucoside (6), one phenolic glucoside; (−)-rhododendrin (7) and three benzoic acid derivatives; p-hydroxybenzoic acid (8), gallic acid (9) and methyl gallate (10). It should be noted that this is the first report of compounds (2) and (6) in Cistaceae family. The structures of the isolated compounds were determined by comprehensive 1D and 2D NMR analysis, mass spectrometry, IR and by comparison with literature data.Graphical abstract
