Das Verhalten von Oxynikotin beim Verrauchen von Zigaretten

Chemical composition of tobacco and tobacco smoke

“…The purines and pyrimidines listed therein occur in the free state; the presence of free xanthine in leaf is doubtful and free hypoxanthine is absent (331). Oxynicotine (nicotine N-oxide) has been claimed to occur in cigarette smoke (244); however, this alkaloid is thermolabile and cannot be recovered in the smoke from cigarettes containing added oxynicotine (428). Levels of metanicotine in leaf have appeared in an agronomic study but proof of identity was not provided (405).…”

“…The formation of PAH from the following carbohydrates and related leaf components has been demonstrated: xylose, glucose, sucrose, maltose, fructose, starch, cellulose, xylan, pectin, and lignin (180,201,450). Suggestions of a relationship between the cellulose content of leaf and the PAH level of smoke (363,427) have led to detailed studies on the pyrolysis of this polysaccharide. Two mechanisms are evident for the formation of BAP from cellulose depending on whether heat is applied isothermally in a series of steps from 450 to 880°or is programmed over this range (450).…”
