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, and lutein.

摘要:
A process for producing (.+-.)-2,2,2,5a-tetramethyl-1-(carboxymethyl)-2-hydroxydecalin, comprising the steps of allowing a carbonate of dihydro-.beta.-vinyl-ionol to react with carbon monoxide in the presence of a palladium catalyst to form .beta.-monocyclohomofarnesic acid, cyclizing said .beta.-monocyclohomofarnesic acid in the presence of an acid catalyst to form (.+-.)-norambreinolid, and hydrolyzing said (.+-.)-norambreinolide to form (.+-.)-2,5,5,8a-tetramethyl-1-(carboxymethyl)-2-hydroxydecalin.
