A new insecticidal sesquiterpene from a mangrove endophytic fungus <i>Aspergillus</i> strain sp. GXNU R1
An undescribed sesquiterpene guxinusocapsa A (<b>1</b>), featuring a unique 5/7/6 tricyclic skeleton, and three known compounds (<b>2-4</b>) was isolated from the mangrove endophytic fungus <i>Aspergillus</i> sp. GXNU R1. These isolates were established primarily through NMR data analysis. The new structure's absolute configuration of <b>1</b> was identified by its single-crystal X-ray diffraction analysis. Compound <b>1</b> showed strong activity towards the Asian citrus psyllid (<i>Diaphorina citri</i>) with 95% lethal at 1000 mg/kg.
