Abstract
A detailed examination of the metabolites produced in liquid cultures by a strain of Trichoderma harzianum, isolated from wheat roots, has resulted in the identification of a further five metabolites. Two of these, cyclonerodiol [5] and the octaketide keto diol 6, have previously been isolated from a strain of Trichoderma koningii. The structures of the three new octaketide-derived compounds 7,8, and 10 have been deduced from spectroscopic and chemical studies. All newly isolated compounds show antibiotic activity towards the take-all fungus, Gaeumannomyces graminis var. tritici.
