Characterization and bioactive potentials of secondary metabolites from .

A search for bioactive secondary metabolites from the endophytic fungus , isolated from the root of , led to the isolation of three indole derivatives (), three cyclohexadepsipeptides (), and four pyrones (). The structures of new () and known compounds () were elucidated on the basis of extensive spectroscopic analysis. All these compounds were evaluated for phytotoxic, antimicrobial activities, and brine shrimp lethality. Compound showed significant phytotoxic activity against the radicle growth of , even better than the positive control of 2,4-D. Cyclohexadepsipeptides () and pyrones () exhibited brine shrimp lethality, especially and with the LD values of 2.78 and 7.40 μg mL, respectively, better than the positive control.
