Cinnamic acid, alphapinene, ethyl cinnamate and vanillin are just some that have been isolated.
methyl butanoate, ethyl butanoate, ethyl pentanoate, ethyl 2-methyl butanoate, ethyl hexanoate, hexyl 3-methyl butanoate, 3-methylbutyl acetate, and ethyl cinnamate. Carbonyl, alcohol or aromatic compounds were e.g.
In contrast to this, the persistence of the following odorants, methyl butanoate, ethyl butanoate, ethyl 2-methylbutanoate, ethyl hexanoate, methional, hexyl 3-methylbutanoate, 3-methylbutyl acetate, [beta]-damascenone, 2-methoxyphenol, 2-ethyl-4-hydroxy-5-methyl-3(2H)-furanone and ethyl cinnamate was reduced.
The gas chromatogram showed that the common compound in the active fractions obtained from the bioassay-guided fractionation of the C[H.sub.2][Cl.sub.2] extract was ethyl cinnamate. This vasorelaxant active compound, ethyl cinnamate, was isolated as a colorless oil.

Ethyl cinnamate ([R.sub.f] = 0.55), the bioactive component, was obtained from fractions 14, 15 and 16.

Only esters butyl acetate and 2-ethyl hexanoate were not identified in HS-SPME; however, benzyl acetate, ethyl 3-octenoate, hexyl pentanoate, 1-pentyl-2-propenyl butanoate, 4-oxocyclohexyl acetate, and ethyl decanoate ethyl cinnamate were not identified in the S-HSprocedure.
For Greg La Follette and other Pinot Noir producers, higher concentrations of four esters (ethyl anthranilate, ethyl cinnamate, 2,3-dihydro cinnamate and methyl anthranilate) can enhance the variety's characteristic blackberry, black currant, cherry, plum, raspberry and strawberry flavors.
