Clematis viticella seeds contained a water-soluble growth inhibitor. The inhibitor was partially purified utilizing organic solvent partitioning, polyvinylpolypyrrolidone (PVPP) column chromatography, and high performance liquid chromatography (HPLC). Inhibitory activity was evaluated with a lettuce seed bioassay. The 1/3 X partially purified extract had little effect on lettuce seed germination, but reduced radicle elongation. The inhibitor was a heat stable, acidic compound which did not co-elute with abscisic acid (ABA) and its bioassay activity was unaffected by methylation and demethylation.
