| 中文摘要: |
| 采用生长速率法测定了黄皮植株甲醇提取物对香蕉炭疽病菌等12种植物病原真菌的生物活性.研究结果表明:黄皮植株甲醇提取物,对香蕉炭疽病菌和辣椒炭疽病菌等有一定的活性;在10 mg/mL的浓度下,黄皮果核、树皮、枝叶和花索的甲醇提取物,对香蕉炭疽病菌菌丝生长的抑制率分别为88.83%、84.61%、72.23%和50.11%;黄皮果核甲醇提取物对香蕉炭疽病菌的EC50为4.34 mg/mL。黄皮果核甲醇提取物的石油醚、氯仿、乙酸乙酯和正丁醇萃取组分对香蕉炭疽病菌的活性研究表明,氯仿层的活性最高,抑制率为86.11%。黄皮果核甲醇提取物的氯仿萃取物对香蕉炭疽病菌的EC50为2.37 mg/mL。 |

| The activity of the methanol extract of Clausena lansium(Lour.) Skeels was assayed against 12 kinds of fungi using growth rate methods.The results showed that all methanol extracts displayed antifungal activities against Colletotrichum musae to some extent.The inhibition rate of the methanol extracts of the stone,cortex,leafstalk and scape of C.lansium against C.musae were 88.83%,84.61%,72.23% and 50.11% at 10 mg/mL,respectively.The EC50 of the methanol extract of the stone against C.musae is 4.34 mg/mL.The antifungal activities of petroleum ether,trichloromethane,ethyl acetate,n-butanol extracts against Rhizoctonia solani were also tested,and the results showed that the highest activity was seen in trichloromethane extract,with an inhibitory rate of 86.11%.The EC50 of trichloromethane extract was 2.37 mg/mL. |
