ANTIMICROBIAL ACTIVITY OF CRUDE EXTRACT OF CITRUS HYSTRIX AND CITRUS MAXIMAAbstract
Since plants are used as therapeutic agents, the present study was conducted to evaluate the antibacterial activities of methonolic extracts of different components of Citrus hystrix and Citrus maxima (Red and White) fruit. Studies on the antibacterial activity of methanolic extracts of leaf, peel, and pulp of Citrus hystrix and Citrus maxima (Red and White) fruitwas conducted using agar disc diffusion method. The microorganisms used include Staphylococcus aureus (MTCC 3160), Salmonella typhi (MTCC 3215), Escherichia coli (MTCC 40), Pseudomonas aeruginosa (MTCC 424), Klebsiella pneumoniae (MTCC 3384). The maximum activity was observed against all organisms except Pseudomonas aeruginosa and Klebsiella pneumoniae. The minimum inhibitory concentration ranged between 12.5mg/mL and 200mg/mL depending on microorganism and various extract. Citrus hystrix and Citrus maxima (Red and White) fruit were observed to have antibacterial activity and can be used for medicinal purposes.
