Molecular networking directed discovery of new herbicidin analogues. a Molecular network consisting of all parent ions detected by LC–MS in the extract crude of hcdR2 overexpression strain. b A constellation for potential herbicidins was picked out using herbicidin F as a probe and amplified for displaying. This constellation has ten nodes possessing precursor ions ranging from m/z 508 to 536 [M+H]+ (Node labels show the precursor masses). c Based on the molecular networking results, the ten herbicidin peaks (110) corresponding to the ten nodes were found in the LC–MS spectrum
