RESUMO
Chemical investigation on the rice culture of Corynespora cassiicola J9, an endophyte inhabiting in Blumea balsamifera (L.) DC. resulted in isolation of eight compounds, including a new depsidone derivative, corynether C (1), and seven analogues, corynether B (2), corynetherlactone A (3), corynether A (4), diaryl ether (5), corynesidone C (6), corynesidone D (7), and corynesidone A (8). Their structures were deduced based on 1D and 2D NMR spectroscopy, and HR-ESI-MS data. All of the isolated compounds were evaluated for inhibitory activities against Lissorhoptrus oryzophilus Kuschel by the leaf spray assay. Unfortunately, none of them showed inhibitory effects.
