摘要：

A new antifungal melampolide, 8-angeloyl-1(10),4,11(13)-germacuratrien-12,6-olid-14-oic acid methyl ester, named sonchifolin, as well as three known melampolides, polymatin B, uvedalin and enhydrin, were isolated from leaf extracts of Yacon [Smallanthus sonchifolius (Poepp. and Endl.) H. Robinson]. Sonchifolin exhibited the highest fungicidal activity against Pyricularia oryzae, a fungus causing rice blast disease and the ED(50) value for the spore germination was 22 ppm. This is the first report of these melampolides as fungicidal compounds.
