Duvatrienediol, alkanes, and fatty acids in cuticular wax of tobacco leaves of various physiological maturity

4,8,13-Duvatriene-1,3-diol found in the leaf wax of Nicotiana tabacum was of highest concentration in the wax from young leaves, and quantitatively decreased in importance with leaf age. Tobacco plants in flower had less duvatrienediol than those that were less mature; however, the total wax content did not change with leaf age. Air drying leaves reduced the duvatrienediol concentration. Changes of total fatty acids and n -alkanes with leaf age and air drying were also examined.
