[Secondary metabolites of endophytic fungus Talaromyces malicola hosted in Armadillidium vulgare].
The secondary metabolites of the endophytic fungus Talaromyces malicola hosted in the arthropod Armadillidium vulgare were separated by silica gel column chromatography, gel column chromatography, and semi-preparative high-performance liquid chromatography. Eleven compounds(1-11) were obtained from the ethyl acetate fraction of the fermentation broth of T. malicola, and their structures were identified by NMR, HR-ESI-MS, UV, IR, and ECD. The 11 compounds were talarosesquiterpene A(1),(3β,5α,6α,15α,22E)-5,6-epoxyergosta-8(14),22-diene-3,7,15-triol(2), vermistatin(3), hydroxyvermistatin(4), bercheminol A(5), penicillide(6), lunatinin(7), penipurdin A(8), emodin(9), BE-25327(10), and(-)-regiolone(11). Compound 1 was a new diaporol-type sesquiterpene. Compounds 2, 4-5, and 7-11 were isolated from Talaromyces for the first time.
