Flavonol glycosides found in hydroethanolic extracts from Tilia cordata, a species utilized as anxiolytics

Tilia species, among which is Tilia cordata Mill. (Tiliaceae), have been used in folk medicine as anxiolytic. The hydroethanolic extract was analyzed by using liquid chromatography with mass spectrometry HPLC-DAD-ESI-MS/MS in negative ion mode, and its chemical composition was compared to flavonoids...

Descripción
Sumario:Tilia species, among which is Tilia cordata Mill. (Tiliaceae), have been used in folk medicine as anxiolytic. The hydroethanolic extract was analyzed by using liquid chromatography with mass spectrometry HPLC-DAD-ESI-MS/MS in negative ion mode, and its chemical composition was compared to flavonoids reported as anxiolytics. The major flavonoids found were: quercetin-3,7-di-O-rhamnoside, kaempferol-3,7-di-O-rhamnoside and kaempferol 3-O-(6-p-coumaroyl glucoside) or tiliroside. The anxiolytic activity of the genus Tilia has been attributed to the presence of quercetin and kaempferol derivatives, while the anxiolytic activity of T. americana var. Mexicana was attributed to tiliroside, which was also found among the major constituents of this species.
