PURIFIED EXTRACT ISOLATED FROM PSEUDOLYSIMACHION ROTUNDUM VAR. SUBINTEGRUM CONTAINING LARGE AMOUNT OF ACTIVE INGREDIENT, PREPARATION THEREOF, AND PREVENTIVE OR THERAPEUTIC COMPOSITION OF INFLAMMATION, ALLERGY, AND ASTHMA CONTAINING THE SAME AS ACTIVE INGREDIENT
PROBLEM TO BE SOLVED: To provide preparation methods and therapeutic agents or functional health foods of a purified extract containing an active ingredient more abundantly, such as a catalpol derivative derived from the extract of Pseudolysimachion rotundum var. subintegrum.SOLUTION: The purified extract fractionated from the extract of Pseudolysimachion rotundum var. subintegrum with butanol exhibits anti-inflammatory, antiallergic, and antiasthmatic activity stronger than the purified extract obtained by conventional methods, because of abundantly containing active ingredients, such as a catalpol derivative.SELECTED DRAWING: None【課題】シュードリシマキオン・ロツンダム変種スブインテグルムの抽出物に由来するカタルポール誘導体などの有効成分をより豊富に含有する精製抽出物の調製方法および治療剤または機能性健康食品の提供。【解決手段】シュードリシマキオン・ロツンダム変種スブインテグルムの抽出物からブタノールで分画した精製抽出物は、カタルポール誘導体などの有効成分を豊富に含有するため,従来の調製法で得られる精製抽出物よりも強力な抗炎症,抗アレルギーおよび抗喘息活性を示した。【選択図】なし
