Conditions
Avicennia marina demonstrates significant antimicrobial potential through its various crude extracts. Specifically, the plant's butanol extracts exhibit very good antibacterial activity against both gram-positive and gram-negative bacteria, including E.coli and B. cerreus. The plant also shows moderate to good antifungal activity against species such as A.flavus and C.albicans. While aqueous extracts of the plant show low activity against these microorganisms, the butanol-based extracts perform with much higher efficacy. Overall, Avicennia marina acts as an effective agent against these diverse bacterial and fungal pathogens.
Preparations
Avicennia marina is prepared as an extract to investigate various medicinal and biochemical properties. Specifically, the plant's leaves serve as a source for extracts used to treat renal toxicity and study toxicological effects. Researchers also utilize the lower half of A. marina's pneumatophores and the upper half of A. marina's pneumatophores as distinct components for ethanolic extract preparation. Additionally, A. marina's shoots are prepared as an extract to compare antimicrobial, antioxidant, and cytotoxic activities against other plant species. These various preparations allow for a detailed analysis of how different plant parts contribute to overall phenolic content and biological efficacy.
Parts used
Avicennia marina is a versatile mangrove species that offers significant medicinal and nutritional value through its various anatomical structures. The leaves of this plant are particularly notable for containing high levels of flavonoids and phenolics, which contribute to its potent antibacterial properties. Beyond the foliage, the stems serve as a source of unique acidic polysaccharides that exhibit high anticomplementary activity. The fruits of the species are also highly significant, as they are widely used for food and contain triterpenoid saponins with promising antitumor potential.
