Introduction

The study explores the phytochemical and antibacterial properties of Solanum xanthocarpum, a significant medicinal plant from the Solanaceae family. Historically utilized in traditional medicine, this plant is known for treating various ailments, including gonorrhea, rheumatism, cough, asthma, and sore throat. Despite its medicinal relevance, there has been little research on its antibacterial effects, prompting the authors to investigate the antibacterial activity of its extracts from different plant parts. The research specifically examines the sensitivity of these extracts against several bacterial strains, including Escherichia coli, Klebsiella pneumoniae, Salmonella typhi, and Bacillus cereus.

Antibacterial Activity of Solanum xanthocarpum Extracts

The study utilized various solvent extracts (petroleum ether, alcohol, and acetone) obtained from the stem, leaf, and fruit of Solanum xanthocarpum. The antimicrobial activity was assessed by measuring the zone of inhibition around the filter paper discs containing the extracts. Results indicated a high sensitivity of the extracts against Klebsiella pneumoniae and Salmonella typhi, moderate sensitivity against Escherichia coli, and resistance against Bacillus cereus. The qualitative phytochemical analysis revealed the presence of several compounds, including alkaloids, carbohydrates, and flavonoids, likely responsible for the observed antibacterial effects. These findings underscore the potential of Solanum xanthocarpum as an antibacterial agent due to its bioactive phytochemical components.

Conclusion

The results of the study reinforce the antibacterial potential of Solanum xanthocarpum, suggesting it could be a valuable source for developing new antimicrobial agents. Given the historical and contemporary significance of medicinal plants, further investigations are warranted to explore the full scope of this plant's pharmacological properties. The presence of various phytochemicals enhances the understanding of how such natural products could be leveraged in modern medicine, especially in the face of rising antibiotic resistance issues. The authors express their gratitude to colleagues who assisted in the study, recognizing the collaborative effort in advancing research on this important medicinal plant.
