Tagetolone and tagetenolone: two phytotoxic polyketides from Alternaria tagetica

J Agric Food Chem. 2001 Mar;49(3):1228-32. doi: 10.1021/jf000872k.

Abstract

Two new phytotoxic polyketides, tagetolone (1) and tagetenolone (2), in addition to tyrosol and p-hydroxybenzoic acid, have been isolated from the organic crude extract of culture filtrates from the fungal pathogen Alternaria tagetica. Complete characterization of all structures was carried out following a careful analysis of their spectroscopic data (IR, MS, (1)H and (13)C NMR, and 2D NMR experiments).
