The volatile compounds of dried sancho (Zanthoxylum schinifolium), an aromatic plant were extracted bysimultaneous distillation and extraction (SDE) method and identified by gas chromatograph-mass spectrometry (GC-MS).Selected chiral constituents of sancho oil were characterized by enantiodifferentiation using multidimensional gaschromatograph (MDGC)-MS. A total of 57 compounds were identified and quantified, and the major compounds wereidentified estragole, nonanoic acid, octanoic acid, β-phellandrenene, and limonene. Among them, estragol (63.9%) was foundas the predominantly abundant component of sancho. α-Pinene and nerolidol, and β-pinene and linalool were determined tobe enantiomerically pure (100%) for their (S)-form and (R)-form, respectively. The enantiomeric composition of limonene insancho revealed 83.9% purity for the (S)-enantiomer, whereas (E)- and (Z)-rose oxides showed mixtures of both enantiomers.The enantiomeric excess (%) for citronellal was 22.6% with the (R)-enantiomer as major enantiomer. The enantiomericcomposition of these compounds can be used as parameter for authenticity control of sancho.
