The Metabolism of the Organic Acids of Tobacco Leaves
In an earlier study of the effect of culture of excised tobacco leaves in darkness in solutions of a number of common organic acids (1)) it was noted that the behavior of the malic and citric acids in leaves cultured in (+)tartrate differed little if at all from that observed in the control samples cultured in solutions of inorganic salts. However, the so called “unknown acid” fraction, i.e. th...
متن کاملThe Metabolism of the Organic Acids of Tobacco Leaves
Preliminary experiments have shown (1, 2) that, when excised tobacco leaves are cultured in the dark in 0.2 M solutions of potassium succinate or L-malate, a marked stimulation of the formation of citric acid occurs. Furthermore, leaves cultured in succinate increased in their content of malic acid, although culture in L-malate, in the single experiment that has been carried out (2), did not le...
متن کاملThe Non-volatile Organic Acids of Green Tobacco Leaves*
Accurate information on the organic acids of leaves is surprisingly meager; even the identity of the acidic substances in many of the plant tissues that have been investigated is still in doubt. Franzen and Keyssner (1) pointed out some years ago that the identity of the malic acid had been conclusively proved in only 15 of 235 plants reported in the literature to contain this substance and a s...
متن کاملEssential fatty acids extracted from Portulaca oleracea L. leaves
Background & Aim: Purslane (Portulaca oleracea L.), belongs to the Portulacaceace family, grows in many parts of Iran. Results of previous studies were indicated purslane is a rich source of essential fatty acids of omega-3 and omega-6. Portulaca oleracea is a widespread weed, being the eighth common plants of the world. The Aim of current study was to compare the essential f...
متن کاملPreparative Chromatographic Isolation of Hydroxy Acids from Lesquerella fendleri and L. gordonii Seed Oils1
To conduct product development research on Lesquerella seed oils, we explored methods to obtain >100 g quantities of lesquerolic (14-hydroxy-cis-lleicosenoic) acid. Preliminary experiments with opencolumn silica gel chromatography showed that L. fendleri oil could be separated into 3 triglyceride (TG) fractions. The first (10%) contained nonhydroxy 16(13%) and 18-carbon acids (65% 18:1,2,3). Th...
