Decay resistance of Pterocarpus erinaceus Poir. and the antifungal properties of its extract

The processing residue of Pterocarpus erinaceus was used to obtain an ethanol-extract, whose anti-fungal properties and mode action investigated using multi-omics principles gas chromatography-mass spectrometry. results showed that the decay resistance heartwood in Grade I; it strong resistance. effective concentration 70% ethanol extract 13.8%. It high inhibition against Coriolus versicolor Gloeophyllum trabeum, content positively correlated with diameter zone. Transcriptomics analysis there were 93 genes differentially expressed trabeum. Among them, 42 up-regulated 51 down-regulated. These mainly related oxidoreductase activity, integral components membrane, carbohydrate metabolism, lipid other trabeum life activities. In total, 31 substances separated observed GC-MS, their peak areas accounted for 91.8% total area. Of these, 16 including ketones, esters, amines, alkanes, olefins aromatic compounds a relatively content. Ketones most abundance at 29.1%. may represent main active antifungal
