Three new pseudo-disesquiterpenoids, vernodalidimer F – H (1 – 3), which are formed by esterification of two sesquiterpenoids, along with a new sesquiterpenoid (4) and two known sesquiterpeonids (5, 6) were isolated from the seeds of Vernonia anthelmintica. Their structures were elucidated by NMR data. The absolute configurations of 1–3 and 5 were determined by comparison of the experimental and calculated...
Three illudin sesquiterpenoids, craterellins A–C, and one gymnomitrane sesquiterpenoids, gymnomitr-3-en-10β,15-diol, were isolated from cultures of the basidiomycete Craterellus cornucopioides, along with four previously reported compounds: illudin F, illudin M, illudin T and illudalenol. Structures of new compounds were elucidated on the basis of extensive spectroscopic analysis and their cytotoxic...
