Abstract: An insect-repellent or insecticidal composition comprising an extract or an organic solvent fraction of oak vinegar as an effective ingredient, is provided. The composition comprising extract or organic solvent fraction of oak vinegar as an effective ingredient has superior insect-repellent or insecticidal activities against lasioderma serricorne, which damages tobacco, grains, paper or clothes, reticulitermes speratus kyushuensis Morimoto, which chews the woods from within, or sitophilus oryzae, which has strong tolerance to insecticides, and therefore, can be applied efficaciously as an insect-repellent or insecticidal composition to conserve wooden furniture, an old house, or many organic cultural heritages.

Abstract: Disclosed herein is an insect proof or insecticidal composition for the conservation of cultural properties against termites, comprising an extract of Asarum sieboldii as an active ingredient. Based on a methanol extract of Asarum sieboldii or a hexane fraction from the methanol extract, the composition is environmentally friendly and non-toxic to humans and animals. Also, because of its excellent insecticidal activity against termites, the composition can be used to protect wooden structures and cultural properties from termite damage, which is a great threat to the life of wooden structures and cultural properties, without toxicity to humans and animals.

Abstract: An insect-repellent and insecticidal composition comprising extract or fraction of phellodendron amurense as an active ingredient is provided. The extract of phellodendron amurense, or the hexane (Hex) extract, methylene chloride (MC) fraction, or ethyl acetate (EtOAc) fraction provides insect-repellent or insecticidal activities against lasioderma serricorne which harms tobacco, crops, paper, clothes or wood, or against sitophilus oryzae which has strong tolerance to insecticide, and thus can be effectively applied as an insect-repellent or insecticidal composition to conserve wooden furniture, an old house, or many organic cultural heritages.
