烟碱在有机羧酸的条件下被对氨基苯磺酸氧化,生成芳香胺类物质,并与氯氰络合物结合(实为氯化氰,它由氰化钾和氯胺一T在线反应产生;CNC1能与吡啶反应生成戊烯二醛),生成淡黄色的混合物。这种混合物在波长460nm处有最大吸收峰。其它吡啶类生物碱也有类似情况,但由于其含量极少,故影响不大。

Nicotine is oxidized by p-aminobenzene sulfonic acid to produce arylamines in the presence of organic carboxylic acid, it will combine with cyanogen-chloride complex (actually Cyanogen chloride, which produced by on-line reaction of potassium cyanide and chloramine-T; CNC1 can reaction with pyridine to produce glutaconaldehyde), to porduce a yellowish mixture. This mixture has a maximum absorption peak at the wavelength of 460nm. It is similar with other pyridine alkaloids, but the effect is not significant due to their low content.
