Approximately 75% of rural livestock owners in the Eastern Cape province of South Africa use plants or plant based remedies to treat their livestock. Prominent among these plants are Combretum caffrum, Salix capensis and Schotia latifolia. Water, methanolic and acetonic extracts as well as decoctions of the three plants were screened against ten bacteria and five fungi. The results of the antibacterial assay indicated significant activity against all the Gram-positive bacteria tested with the minimum inhibitory concentrations ranging from 0.1 to 5.0 mg/ml. A few of the extracts showed minimal activity, but the majority of extracts were not active on the Gram-negative bacteria. Generally, all the extracts showed some antifungal activity against the five test fungi. Methanolic extracts exhibited higher fungal growth inhibition, whereas the water extracts showed the least inhibition. It was noteworthy that some water extracts promoted fungal growth.
南非东开普省约75%的农村牲畜养殖户使用植物或植物性药物来治疗他们的牲畜。这些植物中突出的有南非风车子、南非柳和宽叶肖槿。对这三种植物的水提取物、甲醇提取物、丙酮提取物以及煎剂针对十种细菌和五种真菌进行了筛选。抗菌试验结果表明,对所有测试的革兰氏阳性菌均有显著活性,最低抑菌浓度范围为0.1至5.0毫克/毫升。少数提取物显示出最低活性,但大多数提取物对革兰氏阴性菌无活性。总体而言,所有提取物对五种测试真菌均表现出一定的抗真菌活性。甲醇提取物表现出更高的真菌生长抑制作用,而水提取物的抑制作用最小。值得注意的是,一些水提取物促进了真菌生长。
