title: Rapid characterization of the sucrose esters from oriental tobacco using liquid chromatography/ion trap mass spectrometry.
abstract: Sucrose esters (SEs) from oriental tobacco are normally characterized by gas chromatography/mass spectrometry (GC/MS) after a long saponification and derivatization procedure. To simplify the process, a rapid method has been developed by using liquid chromatography coupled with electrospray ion trap mass spectrometry (LC/ESI-MSn). Using the characteristic fragmentation behavior of abundant SEs identified by GC/MS after purification by gel permeation chromatography (GPC) from cuticular waxes of green oriental tobacco leaf, two types of SEs from green and cured oriental tobacco were identified by MSn analysis. The first is one of three types reported formerly and has 13 SE homologues. However, the presence of unsaturation in one of the acyl substituents of this first type gave rise to a new series with three homologues. The other was found to be a new type and had three homologues. The proposed method enables the rapid and sensitive characterization of SEs from oriental tobacco.
