Title (EN) A METHOD FOR DETERMINING THE LEVEL OF A POLYCYCLIC COMPOUND OF INTEREST PRESENT ON THE SURFACE OF A TOBACCO LEAF
(FR) PROCÉDÉ DE DÉTERMINATION DU TAUX D'UN COMPOSÉ POLYCYCLIQUE D'INTÉRÊT PRÉSENT À LA SURFACE D'UNE FEUILLE DE TABAC
Abstract:
(EN) There is provided a method for determining the level of a polycyclic compound of interest present on the surface of a tobacco leaf, the method comprising the steps of: (a) washing the surface of the tobacco leaf with a solvent, the solvent comprising at least a non-polar solvent, such that no greater than about 10 wt.% of the polycyclic compound of interest present on the surface of the tobacco leaf is removed from the surface of the tobacco leaf; (b) collecting the solvent from step (a); and (c) subjecting the collected solvent to fluorescence spectroscopy to determine the level of the polycyclic compound of interest.
(FR) L'invention concerne un procédé qui permet une détermination du taux d'un composé polycyclique d'intérêt présent à la surface d'une feuille de tabac, le procédé consistant : (a) à laver la surface de la feuille de tabac avec un solvant, le solvant comprenant au moins un solvant non polaire, afin que pas plus d'environ 10 % en poids du composé polycyclique d'intérêt présent à la surface de la feuille de tabac ne soient retirés de la surface de la feuille de tabac ; (b) à récupérer le solvant de l'étape (a) ; (c) à soumettre le solvant récupéré à une spectroscopie de fluorescence pour déterminer le taux du composé polycyclique d'intérêt.
