Secondary Metabolites from the Root Rot Biocontrol Fungus Phlebiopsis gigantea

Molecules. 2018 Jun 12;23(6):1417. doi: 10.3390/molecules23061417.

Abstract

Three cyclopentanoids (phlebiopsin A⁻C), one glycosylated p-terphenyl (methyl-terfestatin A), and o-orsellinaldehyde were isolated from the biocontrol fungus Phlebiopsis gigantea, and their structures were elucidated by 1D and 2D NMR spectroscopic analysis, as well as by LC-HRMS. The biological activity of the compounds against the root rot fungus Heterobasidion occidentale, as well as against Fusarium oxysporum and Penicillium canescens, was also investigated, but only o-orsellinaldehyde was found to have any antifungal activity in the concentration range tested.

Keywords: Heterobasidion spp.; Phlebiopsis gigantea; biocontrol; cyclopentanoids; p-terphenyls; phanerochaetaceae; secondary metabolite characterization.
