A novel phytotoxic nonenolide, (6 S ,7 R ,9 R )‐6,7‐dihydroxy‐9‐propylnon‐4‐eno‐9‐lactone ( 1 ), was isolated from solid cultures of the endophytic fungus Phomopsis sp. HCCB03520, together with three known compounds, cytochalasin H ( 2 ), cytochalasin N ( 3 ), and epoxycytochalasin H ( 4 ). The structures of these compounds were elucidated through spectroscopic analysis, and the absolute configurations were determined by CD spectroscopy. Phytotoxic activities of compounds 1 – 4 were also investigated. Compound 1 showed phytotoxic activity on germination and radicle growth of Medicago sativa, Trifolium hybridum , and Buchloe dactyloides.
