A bioassay-guided fractionation of the phytotoxic crude extract ofAlternaria solani resulted in theisolation of two phytotoxic metabolites identified as zinniol(1) and a new polyketide: homozinniol(2). A third metabolite,6-[(3',3'-dimethylallyl)oxy]-4-methoxy-5-methylphthalide(3) was also isolatedand identified. Structural assignment of the metabolites was basedprimarily on the analysis oftheir mass spectrometry and ¹H NMR spectroscopydata.Keywords: Alternaria solani; Solanum tuberosum;Lycopersicon esculentum; phytotoxin; zinniol;homozinniol; polyketide; phthalide
