Abstract
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, and lutein.
Claims21
A method of extracting and isolating compounds from plants of the Nicotiana species, comprising:
- receiving a plant material of the Nicotiana species;
- contacting the plant material with a solvent for a time and under conditions sufficient to extract one or more desired compounds from the plant material into the solvent;
- separating the solvent containing the one or more desired compounds from the extracted plant material;
- and
- purifying the solvent containing the one or more desired compounds to provide an isolate comprising at least about 75 percent by weight of the one or more desired compounds, the one or more desired compounds being selected from the group consisting of solanone, neophytadiene, megastigmatrienone, β-damascenone, norsolanadione, cis-abienol, α-cembratrienediol, β-cembratrienediol, sucrose esters, lutein, degradation products thereof, and mixtures thereof.
A method for providing a flavor material derived from a plant of the Nicotiana species for addition to a tobacco composition, the method comprising:
- receiving a plant material of the Nicotiana species;
- contacting the plant material with a solvent for a time and under conditions sufficient to extract one or more desired compounds form the plant material into the solvent;
- separating the solvent containing the one or more desired compounds from the extracted plant material;
- purifying the solvent containing the one or more desired compounds to provide an isolate comprising at least about 75% by weight of the one or more desired compounds, the one or more desired compounds being selected from the group consisting of solanone, neophytadiene, megastigmatrienone, β-damascenone, norsolanadione, cis-abienol, α-cembratrienediol, β-cembratrienediol, sucrose esters, lutein, degradation products thereof, and mixtures thereof;
- and
- adding the isolate to a tobacco composition adapted for use in a smoking article or a smokeless tobacco composition.
