- Abstract
Two new ergostane derivatives, 12 β,15 α,25,26-tetrahydroxyergosta-4,6,8(14),22-tetraen-3-one ( 1) and 12 β,15 α,25,28-tetrahydroxyergosta-4,6,8(14),22-tetraen-3-one ( 2), and a new aranotin-type diketopiperazine, bisdethiobis(methylsulfanyl)apoaranotin ( 3), were isolated from the fungus Aspergillus terreus BCC 4651. The structures of the new compounds were elucidated by means of NMR spectroscopic and MS analyses.
