alpha-Tocopherol (alpha-T) has been identified, using gas chromatography-mass spectroscopy and (1)H- and (13)C-nuclear magnetic resonance, in senescing leaves of Melia azedarach L. The content of alpha-T increased concomitantly with the breakdown of chlorophyll in senescing Vinca and Melia leaves. An increase in alpha-T was found also in detached Melia leaves, senescing in either light or darkness and in senescing, ethylene-treated orange leaves and fruit. The possibility that phytol, which is… CONTINUE READING
