Abstract

In this paper, we reported a simple method for determining the enantiomeric purity of  nicotine extracted from tobacco leaves by 13C-NMR spectroscopy using a chiral shift reagent Ytterbium(III) tris[3-(trifluoropropylhydroxy-methylene)-l-camphorate] (Yb(tfc)3). The results showed that the studied native nicotine contained 98% S-Nicotine and 2% R-Nicotine. The geometric parameters of Yb(tfc)3-Nicotine complex were calculated by means of  well-known McConnell-Robertson equation.
