| 摘 要： | 以黄瓜白粉菌、黄瓜霜霉菌、黄瓜炭疽菌、番茄灰霉菌、番茄叶霉菌为供试菌,测试了土木香甲醇、乙醇提取物以及乙醇提取物不同萃取组分的抑菌活性。结果表明:土木香的不同溶剂提取物对5种供试菌都有一定程度的抑制作用,乙醇提取物比甲醇提取物抑菌活性高。土木香乙醇提取物在浓度为0.005 g/mL时,对黄瓜白粉菌、黄瓜霜霉菌的抑制率分别达到99.95%,96.30%。在乙醇提取物不同的萃取组分中,石油醚部分的抑菌活性最强。 |

| Abstract: | The antifungal activities of methanol extract and ethanol extract from Inula,helenium and different extract component from ethanol extract against Sphaerotheca fuliginea,Pseudoperonospora cubensis,Colletotrichum orbiculare,Botrytis cinerea,Fulvia fulva were tested.The results indicated that extracts with different solvents exhibited different inhibitory activity against the five pathogens and the ethanol extract of I.helenium showed stronger antifungal activities than the methanol extract.Ethanol extract of I.helenium at 0.005 g/mL provided 99.95% inhibition against S.fuliginea and 96.30% inhibition against P.cubensis.Furthermore,inhibition effect of petroleum ether phase was stronger than the other different extract component from ethanol extracts. |
