香樟叶提取液的除草与抑菌活性

Herbicide and Antibacterial Activity of the Extracts from Leaves of Cinnamomum Camphora

研究了香樟叶提取液对萝卜、水稻、反枝苋、小麦和大肠杆菌、枯草芽孢杆菌、金黄色葡萄球菌、青霉菌生长的抑制作用。结果表明,乙醇提取液对植物种子萌发、芽长、根长的抑制率分别为100%、75%～79%、85%～89%;水提取液对种子萌发、芽长、根长的抑制率分别为31%～100%、37%～65%、38%～77%。香樟叶提取液对供试菌的抑菌圈直径为13～25mm。香樟叶乙醇提取液比水提取液的抑制作用更大,且对不同植物及菌类的生长抑制效果存在明显差异。

The antibacterial activity of extracts from leaves of Cinnamomum camphora to the E. coli,Bacillus subtilis, Staphyloccus aureus and herbicide effect on radish, wheat, rice, A. retroflexus were investigated. The result showed that ethanol extracts had a significant inhibition on seed germination, seedling length and root length, the inhibitory ratio was 100%, 75 % -79%, 85 % -89% respectively;Water extracts had a inhibition effect on seed germination, seedling length and root length with the ratio was 31% -100% ,37% -65% ,38% -77% respectively. Diameter of inhibiting bacteria circle were 13 -25ram to E. coli, Staphyloccus aureus, Bacillus subtilis. Inhibiting effect of ethanol extracts was greater than water extracts, and different inhibiting effects on different plant and different bacteria strains were observed.
