Seven novel fungitoxic sesquiterpenoids, chokols A, B, C, D, E, F and G, were isolated from stromata of Epichloe typhina on Phleum pratense.Their structures were determined by spectroscopic methods.The absolute configuration of chokol E was elucidated by its CD spectrum with Eu(fod)3 and a chemical correlation with epicyclonerodiol oxide.
