Chemical profiling by UHPLC-Q-TOF-HRESI-MS/MS and antibacterial properties of (Fabaceae) constituents.

A rapid untargeted UHPLC-Q-TOF-ESI-MS/MS-Based metabolomic profiling of the medicinal plant was performed. A total of 18 metabolites were detected, of which 10 could not be identified. Based on this result, an extensive chemical investigation of the CHCl-MeOH (1:1) extract of this plant was carried out, leading to the isolation of a new ceramide, named entadamide (), together with nine known compounds: monomethyl kolavate (), 24-hydroxytormentic acid () chondrillasterol (), 3---D glucopyranosylstigmasterol (), 3---D glucopyranosylsitosterol (), quercetin 3'-methylether (), 2,3-dihydroxypropyl icosanoate (), 2,3-dihydroxy-propyl 23-hydroxytricosanoate () and 2,3-dihydroxy-propyl 24-hydroxytetracosanoate ().
