| Popis: | In the present study, we are interested to investigate the biological activities and nutritive values of Limoniastrum guyonianum leaves and stems. Chemical analysis showed that the most abundant constituent of the volatile fractions identified was the camphor. The evaluation of the antioxidant activities demonstrated great differences depending on the tested organ. Indeed, methanolic leaves extract was more effective to inhibit DPPH radical and to reduce Fe3+. However, stems extract exhibited the highest radical scavenging of ABTS+. Stems and leaves extracts showed similar antibacterial effects against E. coli, S. aureus, and E. faecalis (MIC = 0.156, 3.12 and 0.156 mg/mL, respectively). Stems extract was the best inhibitor of P. aeruginosa growth (MIC = 0.156 mg/mL). The nutritive values showed that leaves and flowers contained the highest levels of protein that varying between 11.55 % for leaves and 12.6 % for flowers. The lipid content ranged from 14.2 0% for leaves and 12.66 % for flowers. This species can have economic potentiality and may be developed as forage for animals or industrial ingredients for various uses in cosmetic and alimentary industries. |
