Abstract: The unorganized callus of Ziziphus nummularia (Burm. f.) Wight & Arn. was raised and maintained on Murashige and Skoog’s medium by frequent subculturing. Various parts and the unorganized callus were examined for potential antimicrobial activity by preparing their crude extracts in water and ethanol and testing them against Gram- positive, Gram-negative bacteria and fungal pathogens. The results obtained indicated that the ethanolic extracts were potent wih a broad spectrum of activity. The results of this study suggest that a number potentially active antimicrobial agents may be btained from this arid zone plant.

Key words: Ziziphus nummularia, unorganized callus, plant parts, antimicrobial activity
