The antibacterial activity of acetone, hexane, dichloromethane leaf extract of five Terminalia species (Terminalia alata Heyne ex Roth., Terminalia arjuna (Roxb.) Wt. and Am., Terminalia bellerica (Gaertn.) Roxb., Terminalia catappa L. and Terminalia chebula Retz.) were tested by Agar-well-diffusion method against human pathogens E. coli, Pseudomonas aeruginosa, Bacillus subtilis, Staphylococcus aureus and Staphylococcus epidermidis. The Rf values and relative activities of separated compounds were tested. Hexane and dichloromethane extracts have shown more antibacterial components than the acetone extract indicating the non-polar character of the antibacterial compounds. The non-polar character of the antibacterial compounds was confirmed from the Rf values. It indicated that the antibacterial activity was not due to tannins. Terminalia catappa found to possess the compounds which are more antibacterial. Terminalia arjuna and T. catappa plants were found most promising for isolating antibacterial compounds.
采用琼脂扩散法，对五种诃子属植物（翼核果诃子、阿朱那诃子、毗黎勒诃子、榄仁诃子和柯子）的丙酮、己烷、二氯甲烷叶提取物针对人类病原体大肠杆菌、铜绿假单胞菌、枯草芽孢杆菌、金黄色葡萄球菌和表皮葡萄球菌的抗菌活性进行了测试。对分离出的化合物的比移值（Rf值）和相对活性进行了检测。己烷和二氯甲烷提取物显示出比丙酮提取物更多的抗菌成分，表明抗菌化合物具有非极性特征。从比移值证实了抗菌化合物的非极性特征。这表明抗菌活性并非源于单宁。发现榄仁诃子含有更多的抗菌化合物。发现阿朱那诃子和榄仁诃子在分离抗菌化合物方面最具潜力。
