Abstract :
[en] The aim of the present study was to isolate and characterize compounds responsible of the antiradical and antibacterial activities in the hydro-ethanolic crude extract of Erythrina excelsa stem bark. Chemical investigation of this polar extract resulted in the isolation of a fructose derivative identified as ethyl-β-D-fructofuranoside (3) and an alkaloid designated L-(+)-Abrine (4); two compounds isolated here for the first time from the genus Erythrina, along with a mixture of sitosterol 3-O-β-D-glucopyranoside (2) and stigmasterol 3-O-β-D-glucopyranoside (1). Their structures were determined using spectroscopic methods (IR, 1 & 2D NMR) as well as HR-ESI-MS and literature data. The hydro-ethanolic extract and compound 3 were tested for antibacterial activity on Escherichia coli, Salmonella typhi, Salmonella typhimurium and Salmonella enterica, and for antioxidant activity using free radical scavenging (DPPH) and Ferric Reducing Ability Power (FRAP). Compound 3 showed good antiradical potential (IC50 21.11 ± 0.53 μg/mL) and moderate antibacterial activity against all the tested bacteria with MIC of 200 μg/mL. For the FRAP method, hydro-ethanolic extract showed weak activity with value of 425 mg GAE/g, while Ethyl-β-D-fructofuranoside (3) exhibited a very good reducing power (40 mg GAE/g). Ethyl-β-D-fructofuranoside (3) could, therefore, be responsible for the antiradical activity of the hydro-ethanolic crude extract.
