INSECT-REPELLENT OR INSECTICIDAL COMPOSITION COMPRISING EXTRACT OR FRACTION OF PHELLODENDRON AMURENSE AS AN EFFECTIVE INGREDIENT FOR CONSERVATION OF CULTURAL HERITAGE

摘要

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.
