Abstract

Several phytotoxic metabolites, including a novel compound chaetoglobosini 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.
