摘要： The invention provides a method of extracting and isolating certain compounds from tobacco. The resulting isolate can include more than 90% by weight of a given compound and can be used as a flavor component for tobacco material used in smoking articles and smokeless tobacco compositions. Exemplary compounds that may be present in the isolate according to the invention include, but are not limited to, solanone, neophytadiene, megastigmatrienone, β-damascenone, norsolanadione, cis -abienol, α-cembratrienediol, β-cembratrienediol, sucrose esters, lutein, degradation products thereof, and mixtures thereof.

摘要： Methods of forming cellulosic sugars from the stalk or roots of a plant of the Nicotiana species are provided herein, the methods including i) receiving a tobacco material including at least one of a stalk material and a root material of a harvested plant of the Nicotiana species; ii) delignifying the tobacco material to form a tobacco-derived pulp; and iii) hydrolyzing the tobacco-derived pulp to form a hydrolyzed tobacco product including residual solids and a liquid including at least one tobacco-derived cellulosic sugar. A cellulosic sugar derived from hydrolyzed tobacco material including at least one of a tobacco stalk material and a tobacco root material of a harvested plant of the Nicotiana species is also provided herein. Tobacco products incorporating the cellulosic sugars derived from hydrolyzed tobacco material or products derived from the cellulosic sugar are also provided.

摘要： A method for producing triethyl citrate from one or more plants of genus
Nicotiana is provided. The triethyl citrate can be derived
inter alia from
Nicotiana species biomass or from seed. In certain embodiments, the triethyl citrate is produced by condensation of ethanol, generated by fermentation of starting material derived from tobacco biomass or seed, and citric acid, also derived from tobacco biomass or seed. The invention also provides articles and compositions including tobacco articles and tobacco compositions that include triethyl citrate produced from one or more plants of genus
Nicotiana .

摘要： A tobacco composition for use in a smoking article or a smokeless tobacco composition is provided, the composition including a component derived from a seed of the Nicotiana species. The component can be a seed of the Nicotiana species or a portion thereof in particulate form or in the form of seed isolate derived from a seed of the Nicotiana species. In certain embodiments, the seed isolate is in the form of a chemically transformed seed isolate, the chemical transformation being selected from hydrogenation, acid/base reaction, hydrolysis, thermal treatment, and enzymatic treatment. The invention also provides smoking articles and smokeless tobacco compositions that include the seed components described herein, and methods for preparing a component derived from a seed of the Nicotiana species for addition to a tobacco composition.
