| 摘 要： | 比较了菖蒲、鸢尾、美人蕉三种湿生植物对铜绿微囊藻的抑制效果。结果表明,对藻的抑制作用菖蒲>鸢尾>美人蕉。用6种有机溶剂提取菖蒲干粉中的抑藻活性物质,显示甲醇提取物的抑藻效果最好,48h抑藻率为98.4%。进一步对甲醇提取物进行分离得到8个组分,每个组分都表现出了抑藻活性,其中前两个组分抑藻活性最大,达99.85%和99.26%。 |

| Abstract: | The inhibition effect of three kinds of wetland plants on Microcystis aeruginosa was compared.Results showed that the sequence of inhibition effect of three plants was Acorus calamus,orris and canna.The active compounds from dry powder of Acorus calamus were extracted with six kinds of organic solvents,and methanol extract had the best inhibition effect on the alga,with inhibition rate of 98.4% in 48h.Eight groups were separated from the methanol extract,and the first two groups showed the best inhibition effect on the alga comparing with the other groups,with inhibition rate up to 99.85% and 99.26% respectively. |
| Keywords: | Acorus calamus orris canna allelopathy Microcystis aeruginosa |
