Two new trichothecenes, named 8 α ‐hydroxyroridin H and myrothecin A, along with six known compounds, 8 α ‐acetoxy roridin H, isororidin K, verrucarin A, verrucarin J, verrucarin L and 8 α ‐acetoxy verrucarin L, were isolated from the fermentation broth of a halotolerant fungus Myrothecium sp. GS‐17, which was separated from the soil sample of a salina. Structure elucidation and NMR signal assignments were achieved on the basis of spectroscopy. In addition, compounds 1 and 2 were active against plant pathogenic fungi Rhizoctonia solani and Fusarium oxysporum . Copyright © 2012 John Wiley & Sons, Ltd.
