The antibacterial activities of the methanol and hot and cold aqueous extracts of the leaves of Aspilia africana, Ficus exasperata and Mareya micrantha were bioassayed against three Gram-negative and three Gram-positive bacterial species: Aerobacter aerogenes, Agrobacterium tumefaciens, Bacillus subtilis, Clostridium sporogenes, Escherichia coli and Staphylococcus aureus. The methanol and aqueous extracts of the leaves of Aspilia africana and Mareya micrantha and the undiluted oil of M. micrantha exhibited differential antibacterial activities on both Gram-positive and Gram-negative bacterial species at concentrations ranging from 0.1 to 0.5 g/ml. Extracts of Ficus exasperata leaves were inactive at all concentrations tested.
对非洲紫菀、粗糙榕和小花马瑞雅叶片的甲醇提取物以及热、冷水提取物进行了生物测定，以检测其对三种革兰氏阴性菌和三种革兰氏阳性菌的抗菌活性，这六种细菌分别是产气气杆菌、根癌土壤杆菌、枯草芽孢杆菌、产芽孢梭菌、大肠杆菌和金黄色葡萄球菌。非洲紫菀和小花马瑞雅叶片的甲醇提取物和水提取物以及小花马瑞雅的未稀释精油在浓度为0.1至0.5克/毫升时，对革兰氏阳性菌和革兰氏阴性菌均表现出不同的抗菌活性。粗糙榕叶片的提取物在所有测试浓度下均无活性。
