摘要：
The present disclosure describes methods of obtaining and/or deriving a sugar-enriched extract from plants of the Nicotiana species and methods for incorporation of such extracts into various tobacco compositions. One exemplary method for preparing a sugar-enriched extract comprises contacting Nicotiana plant material with a solvent and extracting sugars into the solvent to form a liquid sugar-containing extract； separating a solid extracted plant material from the liquid sugar-containing extract； clarifying the liquid sugar-containing extract to form a clarified sugar-containing extract and a solids fraction； and isolating the liquid sugar-containing extract to provide a sugar-enriched extract comprising a combined weight of fructose and glucose of at least about 10% by dry weight. In certain embodiments, the sugars of the extract comprise at least about 50% by weight fructose.
