Changes were investigated in trace alkaloid composition of MC-1 (bright) and Burley-21(burley) leaf lamina during curing. Seventeen alkaloids were identified. The total level of trace alkaloids decreased by approximately 60% in both MC-1 (flue-cured) and Burley-21 (air-cured).Although the level of most alkaloids also decreased, 2, 3 -bipyridyl and four nornicotine derivatives, i.e. N-hexanoyl-, N-octanoyl-, 1-(6-hydroxyoctanoyl)- and 1-(7-hydroxyoctanoyl)-nornicotine, increased during curing in both varieties. Differences in the trace alkaloid composition of cured leaf lamina among MC-1 (bright), Burley-21 (burley) and Basma (Orient) were also studied. In all varieties, N-formylnornicotine, nicotyrine, anabasine and cotinine were present at high concentrations relative to the other trace alkaloids. The alkaloids which were present in a relatively high concentration in particular varieties, were as follows : MC-1 ; N-formylanabasine, Burley-21 ; N-hexanoyl- and N-octanoyl-nornicotine, and Basma ; cotinine and N-formylanatabine.
