Antimicrobial activities of the leaf extracts of Cymbopogon citatrus (lemongrass) and Vernonia amygdalina (bitter leaf) and the seed extracts of Garcinia kola (bitter kola) were carried out. G. kola had effect only on Staphylococcus aureus and Escherichia coli with no inhibition on Candida albicans. Ethanol, cold water and hot water extracts of Vernonia amygdalina and Cymbopogon citratus showed inhibition on the three organism but G. kola ethanol, cold water and hot water extracts only inhibited S. aureus and E. coli with no inhibition on Candida albicans. The organism's susceptibility varied with more inhibition to S. aureus and least to Candida albicans.
对柠檬草(香茅)叶提取物、扁桃斑鸠菊(苦叶)叶提取物和可乐果种子提取物的抗菌活性进行了研究。可乐果仅对金黄色葡萄球菌和大肠杆菌有作用,对白色念珠菌无抑制作用。扁桃斑鸠菊和香茅的乙醇提取物、冷水提取物和热水提取物对这三种微生物均有抑制作用,但可乐果的乙醇提取物、冷水提取物和热水提取物仅抑制金黄色葡萄球菌和大肠杆菌,对白色念珠菌无抑制作用。不同微生物的敏感性不同,对金黄色葡萄球菌的抑制作用更强,对白色念珠菌的抑制作用最弱。
