Herbicidin A is an antibiotic with selective herbidical activity against dicots. It was originally isolated from Streptomyces saganonensis in a soil sample by Sankyo (Japan) in 1976. It is the major analog of a family of adenosine-based nucleosides containing a complex tricyclic saccharide. Herbicidin A is soluble in ethanol, methanol, DMF and DMSO.
