    Analysis of free amino acids in tobacco with a new LC/MS/MS procedure

    MOLDOVENAU S.C.(1); ZHU J.(2)
    (1) R.J. Reynolds Tobacco Company, Winston-Salem, North Carolina, USA; (2) Lancaster Labs. Inc., Winston-Salem, North Carolina, USA
    The levels of amino acids in tobacco are important for leaf characterization. They contribute substantially to the level of toxicants in cigarette smoke, and to the sensory properties of cigarettes. The analysis of amino acids in tobacco leaf has been ...
