Hirsutenols D, E and F, new sesquiterpenes from the culture broth of Stereum hirsutum.
New sesquiterpenes, hirsutenols D-F, were isolated from the fermentation broth of Stereum hirsutum, and their structures were determined on the basis of various spectroscopic analyses. Hirsutenols E and F showed significant scavenging activity against superoxide anion radicals with EC50 values of 1.62 and 0.39 mM, respectively.
