Antimicrobial activity of Elaeocarpus sphaericus

Area of Science:

• Phytochemistry
• Microbiology
• Pharmacology

Background:

• Natural products are a rich source of novel therapeutic compounds.
• Elaeocarpus sphaericus is a plant with traditional medicinal uses.
• Investigating plant extracts for antimicrobial activity is crucial for discovering new treatments.

Purpose of the Study:

• To evaluate the antibacterial potential of different Elaeocarpus sphaericus fruit extracts.
• To identify which solvent extracts exhibit the most significant antimicrobial effects.
• To explore the chemotherapeutic relevance of compounds within the plant.

Main Methods:

• Preparation of five different solvent extracts: petroleum ether (PE), benzene (BE), chloroform (CE), acetone (AE), and ethanol (EE).
• Testing antibacterial activity against a panel of 28 gram-positive and gram-negative bacteria.
• Utilizing disc diffusion and plate dilution methods for quantitative and qualitative assessment.

Main Results:

• The acetone (AE) extract exhibited marked antimicrobial activity against ten bacterial strains.
• Benzene (BE) extract showed activity against Salmonella typhimurium and Morganella morganii.
• Ethanol (EE) extract was effective against Plesiomonas shigelloides, Shigella flexnerii, and Sh. sonneii.

Conclusions:

• Elaeocarpus sphaericus fruit possesses significant antibacterial properties.
• Specific solvent extracts, particularly acetone, demonstrate potent activity against key pathogens.
• The presence of alkaloids and flavonoids in the extracts warrants further investigation for drug development.
