Abstract: Based on the important application of the nontoxic and mosquito-repellent green incense, the processing technology of green incense using Chinese medicinal plant of Artemisia annua L. as the major materials was developed. And the anti-bacterial and mosquito-repellent functions of incense were studied. The volatile oil of A. annua was analyzed by GC-MS method. The production properties of incense were evaluated based on the national standard. The results suggested that the optimal material compositions of incense process were A. annua, wood charcoal, elm powder and Atractylodes lancea. The laboratory efficacy test showed that the anti-bacterial mosquito-repellent green incense had strong mosquito-repellent effect. The KT50 was 4 min. The antimicrobial tests implied that the anti-bacterial mosquito-repellent green incense was the broad-spectrum anti-bacteria agent, which could effectively inhibit the growth of five experimental bacteria. The volatile oil of A. annua by GC-MS method included eleven compositions with relative content more than 2.0%. The effect assessments suggested the production properties of appearance and sensory, wet, bending strength, and continuous combustion time reached to the national standards. The combustion property was related to the cross-sectional area of incense.

Key words: anti-mosquito Incense, Artemisia annua L., antimicrobial effect, mosquito repellent, effect evaluation
