Abstract
The volatiles were isolated from fruits of Zanthoxylum simulans Hance using steam distillation and liquid carbon dioxide extraction, respectively, and analyzed by GC, GC−MS (both EI and CI modes), and GC−FTIR. Totally, 43 compounds were identified in the volatiles, including 20 terpenes, 10 alcohols, 8 esters, and 5 other components. Using chemical ionization, only terpenes became protonated ions, for which accurate molecular weights could be obtained. The yield in steam distillation was 1.69% (w/w), while that in liquid carbon dioxide extraction was 6.38% (w/w). The major volatile components (>10%) found in both volatiles were β-myrcene, limonene, 1,8-cineole, and (Z)-β-ocimene. Some minor components, including isobutyl acetate, isoamyl acetate, and α-terpinene, were not found in the extract of liquid carbon dioxide.
