Mosquitoes are carriers of malaria and encephalitis. This study performed for eco-friendly control of mosquitos by using genus Acorus. Several solvents were used for the extraction of genus Acorus; water, ethanol, and methanol. Grinded leaves and roots were also included. Acorus extracts killed mosquito larvae and the ethanol extract showed the best result. Autoclaved Acorus water needed long time to kill mosquito larvae. LT50 of 1 % Acorus calamus decoction was 13.6 hrs and 1 % autoclaved Acorus water was 53.6 hrs. LT50 of 0.05% Acorus calamus rhizome powder was 28.5 hrs. LT50 of 0.5% Acorus calamus leaf powder was 10.8 hrs. LT50 of 0.1 % Acorus calamus decoction was 63.4 hrs and 0.1 % Acorus calamus ethanol extracts was 48.6 hrs and 0.1% Acorus calamus methanol extracts was 53.9 hrs. LT50 of 0.4% Acorus gramineus decoction was 45.5 hrs, 0.4% ethanol extracts was 10.9 hrs, 0.4% methanol extracts was 10.2 hrs. LT50 of ethanol extracts was shorter than other extracts. Acorus calamus rhizome powder could be used for the eco-friendly control of the mosquito larvae.

창포의 뿌리를 주근(main root)과 측근(lateral root)으로 분리하여 3 열풍건조분말의 주된 포화지방산으로는 caprylic acid, pentadecanoic acid, stearic acid 및 heneicosanoic acid 등 10종이 확인되었고, 이들은 각각 주근과 측근의 경우 caprylic acid가 28.35%, 31.44%이었고, 불포화지방산으로는 linoleic acid, palmitoleic acid 및 lin

창포 뿌리를 주근(main mot)과 측근(lateral root)으로 분리하여 열풍건조 분쇄, 분말화한 후 일반성분, 당 및 아미노산등 화학성분을 분석하여 식품학적 특성을 검토하였다. 주근과 측근 건조분말에는 각각 조단백질 12.76%, 9.84%와 조지방 7.43%, 3.42%로 높게 함유하고 있어 에너지공급원과 식물성 고단백질 원료로서의 우수한 영양학적 가치를 가지고 있음을 확인하였다. 유리당으로는 sucrose, stachyose, raf
