Plant hormones from biomass of the purple non‐sulfur bacterium Rhodospiririllum rubrum were isolated for the first time. These compounds show high physiological activities (300–330%) in the cytokinin bioassay. All three detected cytokinins are adenine derivatives, according to spectral analysis. One of them was identified as 6‐(4‐hydroxy‐3‐methyl‐2‐trans‐2‐bytenylamino)‐9‐ß‐D‐ribofuranosylpurine (zeatinriboside) as shown by thin‐layer chromatography and reversed‐phase high‐performance liquid chromatography. The possible functions of bacterial cytokinins are also discussed.
