Two new diterpenic glycosides, virescenosides M (1) and N (2), have been isolated from a marine strain of Acremonium striatisporum KMM 4401 associated with the holothurian Eupentacta fraudatrix. Their structures were determined on the basis of MS and NMR data as β-D-altropyranosido-19-7-oxo-isopimara- 8,15-diene-2α,3β-diol (1) and β-D-altropyranosido-19-isopimara-7,15-diene- 2α,3β,6β-triol (2). Three other altrosides (3-5), identified as virescenosides A, B, and C from the terrestrial strain Acremonium luzulae, were also isolated. The cytotoxic activity of the virescenosides was examined.
