Summary of article contents:
Introduction
Infectious diseases remain a predominant global health challenge, fueled by the rise of multidrug-resistant pathogens that undermine the efficacy of traditional antibiotics. This critical situation has driven researchers to explore alternative treatments, particularly through the screening of medicinal plants for their antimicrobial properties. This study specifically investigates the antibacterial potential of leaf extracts from Citrullus colocynthis (family Cucurbitaceae), a medicinal plant traditionally used for various ailments. The study employs the agar disc diffusion technique to assess the effectiveness of chloroform and acetone extracts against selected bacterial strains.
Antibacterial Activity of Citrullus colocynthis
The investigation revealed that the chloroform and acetone extracts of Citrullus colocynthis exhibit varying levels of antibacterial activity. Notably, the acetone extract demonstrated significant antibacterial effects against Pseudomonas aeruginosa with a zone of inhibition measuring 14 mm, while the chloroform extract showed no activity against Staphylococcus aureus. Moreover, the minimum inhibitory concentration (MIC) for the chloroform extract was determined to be 4 mm for Escherichia coli. The results underscore the influence of solvent choice on the extraction of phytoconstituents, which impacts the antibacterial efficacy of the extracts against different bacterial strains.
Conclusion
The findings of this study emphasize the potential of Citrullus colocynthis as a source of natural antibacterial agents, particularly through its acetone leaf extract. The plant's notable activity against specific pathogens suggests its promise in the development of new therapeutic strategies to combat antibiotic-resistant infections. Further research into the phytochemical composition of these extracts and their mechanisms of action could pave the way for modern chemotherapies derived from traditional medicinal plants, providing effective alternatives in the fight against resistant microbes.
