FRACTIONATED MATERIAL OF WATER EXTRACT OF LEAF OF EUCOMMIA ULMOIDES OLIVER AND ANTIOBESTIC AGENT CONTAINING THE SAME

摘要

PPROBLEM TO BE SOLVED: To provide a fractionation method for efficiently taking out a component of leaf of Eucommia ulmoides Oliver, particularly a pharmaceutical component such as an iridoid compound and to provide a fractionated material of leaf of Eucommia ulmoides Oliver containing a specific component in high concentration and to provide a composition for oral ingestion, a medicinal composition, a food composition, a medicine and a food, each using a natural material as a raw material, which are safe also when taken in the human body over a long period because of little adverse effect. PSOLUTION: The fractionated material of water extract of leaf of Eucommia ulmoides Oliver is obtained by a production method comprising steps for producing a component obtained by adsorbing a water extract of leaf of Eucommia ulmoides Oliver obtained from dried Eucommia ulmoides Oliver into a reverse phase synthetic adsorbing agent and eluting the adsorbed material with water. A medicine and a food each contains the fractionated material of water extract of leaf of Eucommia ulmoides Oliver. PCOPYRIGHT: (C)2007,JPO&INPIT
