| 中文摘要: |
| 以棉花黄萎病菌Verticillium dahliae为供试菌种, 采用菌丝生长速率法测定了25种中草药乙醇提取物的抑菌作用。结果表明, 25种中草药乙醇提取物中, 花椒、黄柏和木香的抑菌作用最好, 抑制率分别为59.30%、48.29%和45.54%。同时, 这3种中草药的乙醇提取物抑菌活性均显著高于石油醚提取物的抑菌活性。在室内毒力测定中, 花椒、黄柏和木香的乙醇提取物对供试菌株的EC50分别为3.74, 13.98和17.02 mg/mL。 |
| 英文摘要: |
| Antifungal activity of 25 kinds of Chinese herbal extract against Verticillium dahliae was tested using the method of the mycelial growth rate. The results showed that alcohol extracts from Zanthoxylum bungeanum Maxim, Phellodendron amurense and Radix Aucklandiae showed strong inhibitory activities to the pathogenic fungi, with the inhibition rates of 59.30%, 48.29% and 45.54%, respectively. Antifungal activities of the alcohol extracts from the three plants were significantly higher than that of the petroleum ether extracts. Indoor toxicity test demonstrated that the EC50 values of the alcohol extract of the 3 plants were 3.74 mg/mL, 13.98 mg/mL和17.02 mg/mL, respectively. |
