Three new diterpene glycosides, virescenosides V (1), W (2), and X (3) have been isolated from a marine strain of Acremonium striatisporum KMM 4401 associated with the holothurian Eupentacta fraudatrix. Their structures have been elucidated on the basis of high resolution mass spectrometry, 1D and 2D NMR (1H, 13C, DEPT, COSY 45, COSY RCT, HSQC, HMBC, and NOESY spectra) as 19-O-beta-D-altropyranosyl-7-oxo-isopimara-8(14),15-diene-2alpha,3beta-diol (1), 19-O-beta-D-altropyranosyl-isopimara-7,15-diene-2 alpha,3 beta,6 alpha-triol (2), and 19-O-beta-D-altropyranosyl-isopimara-8,15-diene-2 alpha,3 beta,7 alpha-triol (3).
