After concentration, essential oils and aroma extracts were studied by gas chromatography (GC) and GC–mass spectrometry (GC–MS). A high proportion of essential oils and aroma extracts consisted of phthalides with 74.6–76.6% in leaves, 56.8–74.1% in stalks and 57.7–79.7% in roots. The studied organs were particularly characterized by appreciable levels of terpene hydrocarbons (17.0–31.5%). Also, results showed that stalks were particularly rich in phenols with 8.7% of total volatiles. The main volatile constituents identified in the different extracts were (Z)-3-butylidenephthalide (27.8–38.4% in leaves, 30.5–38.9% in stalks, 30.5–52.0% in roots), 3-butyl-4,5-dihydrophthalide (34.2–41.0% in leaves, 24.1–27.8% in stalks, 12.3–13.2% in roots) and α-thujene (7.9–9.9% in leaves, 7.5–14.0% in stalks, 7.0–12.4% in roots). The three studied organs of A. graveolens (leaves, stalks and roots) could be considered good sources of phthalides known for their anti-inflammatory, anti-tumor and insecticidal properties. Nevertheless, the efficiency in the extraction of these bioactive compounds depends on both the organ and the method used.
