| 摘 要： | 以丙酮为溶剂采用超声波辅助提取法对11种伞形科植物进行了活性物质提取,采用生长速率法测定了各提取物对7种常见植物病原菌的抑制作用.结果表明:在0.1 g/mL浓度下,11种伞形科植物的提取物均表现出一定的抑菌作用;在0.01 g/mL浓度下,旱芹、阿魏、当归、蛇床四种植物的提取物对2种或2种以上种病原菌的抑制率大于50;.旱芹提取物的活性最好且抑菌谱较广,其对棉花枯萎病的EC50为2 689.0611 μg/mL.旱芹抑菌活性物质及抑菌机理有进一步研究价值.

| Abstract: | The inhibitory effect of 11 Umbelliferae plant acetone extracts were tested by agar dilution method on 7 plant pathogens.The results showed all these 11 Umbelliferae plant extracts showed inhibitory effect under the concentration of 0.1 g/mL;extracts of Apium graveliens,Ferula ferulaeoides,Angelica sinensis, Cnidium monnieri had more than 50%antifungal rate against 2 or more plant pathongens under the concentration of 0.01g/mL.And the extract of Apium graveliens showed strong antifungal activity against Fusarium oxysporium,the EC_(50) was 2 689.061 1μg/mL in 70 h. |
