ANTIMICROBIAL ACTIVITY OF Hibiscus sabdariffa AND Sesbania grandiflora EXTRACTS AGAINST SOME G–ve AND G+ve STRAINS

Abstract

Abstract. Medicinal plants such as Hibiscus sabdariffa and Sesbania grandiflora are widely used to treat different diseases caused by different microbes in several countries. The antimicrobial activities of Hibiscus and Sesbania extracts were examined in present work. The antimicrobial activity of the plant extracts were investigated against Escherichea coli, Staphyloccoccus aureus and Pseudomonas aeruginosa. This study exhibited strong antibacterial activity of the aqueous extract of H. sabdariffa in comparison to S. grandiflora stem and root ethanolic extracts. Results obtained from this study indicate that both extracts exhibited concentration dependent effect. Hibiscus extract showed the highest inhibition activity against all bacterial strains at concentration 500 mg/mL in comparison to Sesbania extract.

Influence of different wild-garlic (Allium ursinum) extracts on the gastrointestinal system: spasmolytic, antimicrobial and antioxidant properties

“…our extracts were less potent (Table ). The results of the antimicrobial assays could be affected by the applied extraction procedures and the active plants secondary metabolites that are produced during plant development in response to various environmental stressors …”

“…The results of the antimicrobial assays could be affected by the applied extraction procedures and the active plants secondary metabolites that are produced during plant development in response to various environmental stressors. [40,41] Antimicrobial activity of a plant extract depends on the organ of the plant used, the type of the solvent used for extraction, the extraction method and type of microorganisms tested. [10,15] Potential thiosulphinates from Allium extracts react with free SH groups of intracellular enzymes and affect intracellular processes and cell communication.…”

Interdisciplinary Character of Biochemistry and Analytical Biochemistry

“…The donor is called the atom that gives the electrons to form the bond, and the acceptor is called the atom takes part in the formation of the link without sharing any electron, that is, the atom adds the donor electron pair. The central atom (the complex generator) together with the ligands form the so-called internal sphere complex [11,24]. The ions, which are not directly connected to the complex generator, form the outer sphere of a complex.…”
