Abstract
The objective of this work was to evaluate chemical composition of essential oils (EOs) extracted by hydrodistillation from different organs of the Zanthoxylum armatum (DC.) ie: leaves, aerial part (a bunch containing unriped fruits along with leaves), unripe and ripe fruits. The EOs metabolites were analyzed using GC/GC-MS (Gas Chromatography/ Gas Chromatography Mass Spectrometry) and NMR (Nuclear Magnetic Resonance). Highest yield was observed in ripe and unripe fruits (1.5% and 1.3%, respectively). Twenty seven different metabolites were characterized in all samples, representing (82.3–96.6%) of the total oils. Extracted EOs were dominated by monoterpenes (26.6–83.0%) and oxygenated (12.5–55.1%) monoterpene hydrocarbons with β-phellandrene (5.3–40.6%), sabinene (0.4–18.5%), β-myrcene (3.8–8.6%), limonene (5.5–12.5%), linalool (0.1–32.4%), terpinen-4-ol (3.0–12.9%), 1,8-cineole (0–11.6%), undecan-2-one (9.8–15.2%) and cis-sabinene hydrate (1.8–6.9%). Our findings revealed a very high quantitative and qualitative variation of EOs composition in among samples.
