Free amino acids from the leaves of ten North American conifer species have been analysed by packed-column gas-liquid chromatography as their N(O,S)-heptafluorobutyryl isobutyl esters. The species examined were Balsam fir [A&es balsumea (L.) Mill], douglas fir [Pseudotsuga menzeisii(Mirb.) France],
An excellent separation of the N-TFA N-butyl esters of seventeen of the protein amino acids was achieved with acid washed Chromosorb W as the support material mesh, dried at 140~ for 12 h). In these experiments, the liquid phase, stabilized EGA, was used at loadings of from 0.325 w/w o/0 to 0.65 w/w
