[Objective] To determine the antimicrobial activities of different extracts from Ceratostigma minus Stapf ex Prain,so as to provide scientific evidence for its further development.[Method] The extracts of Ceratostigma minus Stapf ex Prain were subjected to bacteriostatic tests in vitro by agar spread method.MIC and MBC value were determined by micro-dilution method.[Result] The extracts were endowed with inhibitory effect against Staphylococcus aureus,Escherichia coli,Pseudomonas aeruginosa and Candida albicans in different degrees,among which,the petroleum ether layer of Ceratostigma minus Stapf ex Prain showed strong inhibition activity against the above 4 bacteria with the minimum inhibitory concentrations(MIC) of 0.005,0.078,0.156 and 0.005 mg/ml respectively.[Conclusion] The extracts of Ceratostigma minus Stapf ex Prain have broad spectrum of antimicrobial activity.And this study would provide scientific evidence for further development of Ceratostigma minus Stapf ex Prain.
