Bioactive secondary metabolites from tomato-derived bacterium Hnu24.

A series of secondary metabolites have been isolated from the genus of , most of which show antibacterial and insecticidal activities. In order to find more bioactive secondary metabolites from , one new natural component aminoindole dimer baciindole A (), together with seven known compounds () were isolated from the tomato-derived bacterium Hnu24. The structure of compound was elucidated by its HR-ESI-MS spectral data and 1 D/2D NMR spectroscopic analysis.
