Propiionycholine, a novel analogue of acetylcholine, was identified in green plants by gas chromatography/mass spectrometry. Propionycholine was found in the leaves of the following species previously shown to contain acetylcholine and chlinesterase acitvity. Codiaeum variegatum Blume, Phaseolus aueus Roxb. cv. Berken, Plantago regelli Decne., Populus grandidentata Michx, and Betula pendula Roth. The quantities of propionylcholine ranged from a high of 2.3 nmol (g fresh weight)-1 in C. variegatum to a low of 0.11 nmol (g fresh weight)-1 in P. Rugelli. These amounts represented 6 to 8% of the levels of acetylcholine. In contrast to animals tissues which rarely synthesize propionylcholine, this compound was found in all species examined which represented five families of flowering plants. [ABSTRACT FROM AUTHOR] |
