Cyanamide was isolated from hairy vetch (Vicia villosa Roth), a leguminous plant utilized as a cover crop, guided by plant growth inhibitory activity against lettuce seedlings. The crude extract of hairy vetch contained 130 μg of cyanamide per gram fresh weight. A large portion of the inhibitory activity in the crude extract of hairy vetch was explained by the presence of cyanamide, suggesting that the compound is a possible allelochemical of the hairy vetch. We also demonstrated that cyanamide was biosynthesized in hairy vetch seedlings. This is the first report of cyanamide from a natural source.
