Study on Secondary Metabolites of Endophytic Fungus Ogataea sp. RW-S10 from the Pogostemon cablin

Abstract:

In order to obtain bioactive metabolites from Pogostemon cablin endophytic fungus, seven secondary metabolites were isolated and purified from the patchouli endophytic fungus Ogataea sp. RW-S10 by various chromatographic column techniques. Based on spectral data, their structures were identified as ogataearin (1), phenylalaninol (2), parahydroxyacet-ophenone (3), bis(dethio)bis(methylsulfanyl)gliotoxin (4), N-phenylethyl acetamide (5), lumichrome (6), and dehydroxypaxilline (7). Compound 1 was a new compound and showed α-glucosidase inhibitory activity with IC₅₀ value of 39.38 μmol/L.
