Influence Of PH On Essential Oil Composition Of Zanthoxylum Rhetsa Seeds Obtained By Steam Distillation
Published 2006 · Chemistry
Effect of extraction methods on the composition of Z. rhetsa seed essential oil was examined. The steam-distilled essential oil from the seeds of Z. rhetsa, obtained under three different conditions were analysed by GC and GC–MS, resulting in the identification of 43 constituents. Sabinene (66.74% and 72.7%), β-pinene (6.47% and 6.59%), α-pinene (6.08% and 6.08%) and myrcene (1.48% and 1.6%) were the major components obtained from aqueous and alkaline media, respectively, while α-terpinene (23.68%), γ-terpinene (23.06%), terpinolene (5.66%) and limonene (4.67%) were the main components from acid medium.
