ABSTRACT
Artemisia argyi is a perennial aromatic herb. As been recorded in 2015 edition of Chinese Pharmacopoeia， it has the characteristics of warming meridian to stop bleeding，dispersing cold and relieving pain，and clearing dampness to stop itching in topical use. It contains a variety of active ingredients and has a wide range of edible and medicinal values. It mainly includes essential oil，flavonoids，polysaccharides，tannins and other compounds. The essential oil compounds have antioxidant，anti-inflammatory，anti-tumor and bacteriostatic biological activities. At the same time，they have activities of poisoning，repelling，antifeeding and affecting growth and development for the mosquitoes. In order to further study the activity of essential oil and its chemical components from A. argyi in mosquitoes control，and to improve the development and utilization of mosquito control products，we reviewed the functions of plant essential oil for mosquito control and the existing related dosage forms in this study. Simultaneously，we summarized the extraction methods， mosquito control functions and active ingredients of essential oil， with focus on the action mode and target objects of the active components in volatile oil monomers from A. argyi. Based on the current researches on essential oil of A. argyi in mosquitoes control，the existing problems were analyzed to provide references for the synthesis and application of plant insecticides，environment-friendly pesticides and new insecticides developed as green plant materials，and put forward the prospects on the development of new highly active A. argyi mosquitoes control products.
ABSTRACT
Artemisia argyi is a perennial aromatic herb，which has used as a medicine for its leaves.It is spicy，bitter and warm，it has a small poison，it acts on the liver，spleen and kidney.According to traditional Chinese medicine（TCM），it has the functions of warming the bleeding，relieving cold and pain，dispelling dampness and itching，and so on.Previous researches have shown that A. argyi is used for treatment of various diseases，including pneumonia，gastritis，and hepatitis.Modern pharmacological studies have shown that it has a variety of antibacterial，antioxidant，insect-resistant，anti-inflammatory，immunomodulative and other activities，which depend on their complex chemical constituents，mainly including essential oil，flavonoids，tannins and polysaccharides.The A. argyi essential oil（AAEO）are the main active parts isolated from the extract of A. argyi，including ethers，alcohols，monoterpenes，sesquiterpenes，and other compounds，which have broad-spectrum antibacterial，antioxidant，anti-inflammatory，anti-tumor，analgesia，asthma relief and immune regulation，and have broad-spectrum biological activities.By studying the literatures at home and abroad in recent years，the chemical composition of AAEO was sorted out，and the chemical composition characteristics and contents of it prepared by different extraction methods were summarized，as well as the common chemical components detected in AAEO at the present stage.The author also reviewed a variety of pharmacological activities of AAEO，focusing on its anti-inflammatory，anti-tumor，antibacterial，antioxidant and other activities，and found that it has a good drug development prospect for inflammation，tumor，bacterial diseases and so on.In order to better exploit and utilize AAEO natural resources，the author analyzes the existing problems in the research and development process of it and puts forward that it is necessary to further and systematically explore its chemical components，pharmacological effects，basis of medicinal substances and mechanism of action，so as to lay a foundation for the comprehensive development and utilization of AAEO.
