Description:
A new method for determination of volatile terpenoids in wine is proposed. An off-line solid phase extraction-gas chromatographic method has been used for the determination. The influence of several extraction variables was studied, including the solid phase employed (C-18 versus divinylbenzene-based), eluting solvent (n-pentane, dichloromethane, ethanol and methanol), volume of eluting solvent (1-4ml) and drying time (0-20min). Complete recovery of volatile terpenoids from several kinds of wines was obtained under the optimized conditions.
