PROBLEM TO BE SOLVED: To provide an ipriflavone solubilized composition containing ipriflavone in high concentration by effectively inhibiting crystal deposition of ipriflavone which has poor solubility and high crystallinity.SOLUTION: The ipriflavone solubilized composition is obtained by utilizing essential oil which contains menthones or perillaldehydes such as perilla oil or peppermint oil to dramatically improve solubility of ipriflavone in the formulation, and preventing deterioration of properties of the formulation caused from time-dependent crystalization of the ipriflavone.COPYRIGHT: (C)2012,JPO&INPIT【課題】難溶性で高結晶性であるイプリフラボンの結晶析出を有効に防止した、イプリフラボンを高濃度に含有するイプリフラボン可溶化組成物を提供する。【解決手段】シソ油やハッカ油等のメントンやペリルアルデヒドを含有する精油を用いることにより、イプリフラボンの製剤中の溶解度を飛躍的に向上させ、経時的にイプリフラボンが結晶化して製剤の性状劣化を防止するイプリフラボン可溶化組成物が得られる。【選択図】なし
