PROBLEM TO BE SOLVED: To provide a substantially odorless hygienic repellent hardly causing deterioration in effect due to learning and exhibiting excellent repellent effect over a long period.SOLUTION: A repellent is included in urine of wolves and exhibits repellent effect to mammals except humans and to birds. The repellent has characteristics 1 and 2: 1. the repellent is transferred to an aqueous phase when ether extraction of urine of wolves is carried out with pH of ≥4, while the repellent is precipitated when the ether extraction is carried out with pH of <4 and 2. the repellent is adsorbed to a stationary phase when urine of wolves is passed through the stationary phase including a silicon compound having octadecyl silyl groups, and eluted with a highly polar organic solvent.COPYRIGHT: (C)2013,JPO&INPIT【課題】ほとんど臭いがなく衛生的であり、且つ、学習による効果の低下が生じにくく、長期に亘って優れた忌避効果を発揮する忌避物質を提供する。【解決手段】本発明の忌避物質は、オオカミの尿に含まれるヒトを除くほ乳類、又は鳥類に対する忌避物質であって、下記特性1及び/又は2を有することを特徴とする。1.オオカミの尿をpH4以上でエーテル抽出すると水相に移行し、pH4未満でエーテル抽出すると沈殿する2.オオカミの尿をオクタデシルシリル基を備えるケイ素化合物を含む固定相に通すと吸着し、高極性有機溶媒によって溶離する【選択図】なし
