Antimicrobial activity of sequential extracts from leaves of Cassia nodosa bunch

Abstract

The present study deals with the antimicrobial activity of the sequential extracts (petroleum ether, benzene, acetone, chloroform, ethanol, water, etc.) of the leaves of Cassia nodosa carried out against certain bacteria which are: Staphylococcus aureus, Salmonella typhi, Escherichia coli, Pseudomonas aeroginosa and fungi including, Aspergillus flavus, Aspergillus niger, Fusarium moniliformae and Rhizoctonia bataticola using disc diffusion technique. Results showed that most of the extracts were effective against all the test microorganisms. The minimum inhibitory concentrations of the extracts of chloroform, benzene, acetone and ethanol were found to be 2 × 10 4 µg/ml, while the petroleum ether and water showed no inhibition. The results of the study provide scientific basis for the use of the plant extracts in the treatment of fungal and bacterial diseases. Therefore, the various active principles possessing antimicrobial activity may be extracted from the leaves of C. nodosa by various organic solvents.

Antibacterial Potential Of Orange (Citrus Aurantium) Peels Against Selected Gram-Positive and Gram-Negative Bacteria Isolated From Futa Botanical Garden Soil

“…Long before humanity discovered the existence of microbes, the idea that plants have some healing potential, i.e., that they contain what we will currently characterise as an antimicrobial principle, was well accepted [1]. Using higher plants and their extracts to treat infectious diseases is an age-old practice in traditional African medicine [2].…”

“…Since antiquity, man has used plants to treat common infectious diseases and some of these traditional medicines are still included in the chronic treatment of various disorders [1]. Traditional medicine practitioners use Numerous plants and herbs all over Nigeria as phytomedicine.…”
