NMR spectra for rapid distinction between natural and synthetic nicotine and detection of possible adulteration
1H and 2H NMR spectra of 4 natural and Synthetic Nicotine samples were collected in a non-quantitative way and site-specific 2H/1H peak intensity ratio (SPIR) was calculated for 12 distinct sites of nicotine.
Experimental results illustrated that the SPIRs at sites of 6, 2′, and 5′β of natural nicotine were significantly different from those of the Synthetic Nicotine, and could be used for nicotine authentication as the measured SPIRs were indicative of the site-specific natural isotope fractionation.
