Strobilols A–D: Four cadinane-type sesquiterpenes from the edible mushroom Strobilurus ohshimae

Four cadinane-type sesquiterpenoids, strobilols A, B, C and D, have been isolated from the edible mushroom Strobilurus ohshimae. Their structures were established on the basis of spectroscopic analysis. Four sesquiterpenoids – strobilols A ( 1), B ( 2), C ( 3), and D ( 4) – were isolated from the organic extracts of fruiting bodies of the edible mushroom Strobilurus ohshimae. Their structures were determined by spectroscopic methods. Compound 1 exhibited moderate activity against the brine shrimp Artemia salina. This paper is the first report on isolation of cadinane-type sesquiterpenoids from S. ohshimae.
