Chaetoglobosin O and Other Phytotoxic Metabolites from Cylindrocladium floridanum, a Causal Fungus of Alfalfa Black Rot Disease.
Several phytotoxic metabolites, including a novel compound chaetoglobosin O, were isolated from Cylindrocladium floridanum Sobers et Seymore. The structure of chaetoglobosin O, including its absolute configuration, was determined by a spectroscopic analysis and chemical correlation. Purified chaetoglobosins A, C, and O showed potent growth-inhibition activity against alfalfa seedlings.
