Glycosidic Fraction of Flue-cured Tobacco Leaves: Its Separation and Component Analysis

Abstract

  The fraction containing glycosidic components was separated from flue-cured tobacco (Nicotiana tabacum L.) leaves by a facile method. Some components of the fraction were isolated and elucidated to be syringin, coniferin, cichoriin, benzyl-β-D-glucoside, Blumenol A-β-D-glucoside, and 5,6-epoxy-5,6-dihydro-3-hydroxy-β-ionyl-β-D-glucoside. Syringin and coniferin were detected in the Nicotiana species for the first time.
