Embodiment 1

[0015] The artemisinin derivative artemether was used to conduct acute toxicity experiments on aseptically cultured Microcystis aeruginosa. A number of concentration gradients were set, blanks and two parallel groups were set up, and observations were made every 24 hours for 5 consecutive days. The results showed that when the concentration of artemether reached above 2mg / L, its 96h effective inhibition rate against Microcystis aeruginosa reached above 95%.

Embodiment 2

[0018] The artemisinin derivative artether was used to conduct acute toxicity experiments on aseptically cultured Scenedesmus obliquus. A number of concentration gradients were set, a blank and two parallel groups were set up, and observations were made every 24 hours for 5 consecutive days. The results showed that when the concentration of artether reached more than 2mg / L, its 96h effective inhibition rate against Microcystis aeruginosa reached more than 94%.

Abstract

The invention provides application of artemether as an algae inhibiting agent. Artemisinin simple ether derivatives have a good inhibition effect on copper aluminum microcystis, scenedesmus obliqnus and the like. The artemisinin simple ether derivatives can be prepared into missible oil, clathrate, slow release microcapsules and the like as algae inhibiting agents applied in nature water bodies like ponds, reservoirs and lakes for inhibiting algae booms.

Description

[0001] technical field [0002] The invention belongs to the field of water body pollution control, and particularly relates to the application of traditional antimalarial drug artemisinin simple ether derivatives as algae inhibitors, providing a new application field for artemisinin simple ether derivatives. [0003] Background technique [0004] Artemisinin is an effective monomer component (sesquiterpene lactone peroxide) extracted from the traditional Chinese medicine Artemisia annua, which has excellent antimalarial effect and has been recommended by the World Health Organization as a new antimalarial drug. At present, the main application fields of simple ether derivatives of artemisinin are still antimalarial drugs, antifungal, antibacterial, antitumor, anticancer, antischistosomiasis and other fields, and have not been used as algastatic agents [0005] In the prior art, methods for controlling algal blooms in water bodies mainly include physical methods, chemical m...
