Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for producing an antifungal substance effective against plant anthracnose from garlic skin, and the novel antifungal substance. SOLUTION: The production method of the garlic skin-derived antifungal substance comprises steps wherein (1) garlic skin is prepared, (2) the garlic skin is pulverized if required and subsequently extracted with ethyl acetate to obtain an ethyl acetate extract, (3) the ethyl acetate extract is subjected to flash column chromatography using a developing solvent comprising n-hexane and ethyl acetate to obtain a third-eluted fraction III (Fr.III) and (4) components in the fraction III are subjected to thin layer chromatography using methylene chloride/ethyl ether/n-hexane (10:1:7) as a developing solvent to collect a substance showing an Rf value of about 0.44. The novel antifungal substance is obtained through the same. COPYRIGHT: (C)2006,JPO&NCIPI
