title: Methyl jasmonate increases reported alkamides and ketoalkene/ynes in Echinacea pallida (Asteraceae).
abstract: Methyl jasmonate (MJ), a naturally-occurring plant cellular signal molecule, was found to induce production of lipophilic secondary metabolites in Echinacea pallida seedlings. Seedling aerial parts were sprayed with 100 ppm MJ, and roots were harvested and extracted 24 h later. Lipophilic root extracts, separated by HPLC, revealed significant increases (P< 0.05) in six alkamides or related ketoalkene/ynes produced by 34 day-old plants and in seven compounds produced by 58 day-old plants.
