The steam-distilled essential oil of the foliage contained bornyl acetate (34.2%) as main component, together with α-pinene (12.9%), and camphene (16.4%). Minor components were delta3-carene (5.8%), limonene (4.1%), myrcene (3.7%), β-pinene (2.6%), β-phellandrene (1.0%), isoborneol (0.1%), terpinen-4-ol (0.4%), α-terpineol (1.2%), and trans-carveol (0.1%). Main components found in the hydrosol were α-terpineol, borneol, bornyl acetate, (Z)-3-hexenol, camphenehydrate, and 1.8-cineole." \\ | The steam-distilled essential oil of the foliage contained bornyl acetate (34.2%) as main component, together with α-pinene (12.9%), and camphene (16.4%).

| "...the essential oil of Black spruce (Picea mariana) bark residue was obtained using two types of hydrodistillations: steam distillation (SD) and water distillation (WD). Both gave similar yields and compositions as analyzed using gas chromatography and mass spectrometry. The essential oil composition is turpentine-like with the predominance of α-pinene (40.6% SD; 40.5% WD) and β-pinene (33.9% SD; 25.9% WD), followed by hydrocarbon monoterpenes β-phellandrene (4.8% SD; 3.6% WD), 3-carene (4.1% SD; 3.1% WD), and limonene (4.0% SD; 3.7% WD). Hydrosol’s composition is rich in oxygenated compounds with α-terpineol (29.3% SD; 33.5% WD), trans-pinocarveol (5.2% SD; 3.7% WD), terpinen-4-ol (5.0% SD; 5.8% WD), verbenone (4.9% SD; 5.4% WD), borneol (4.9% SD; 3.9% WD), and pinocarvone (4.6% SD; 4.3% WD). These black spruce bark essential oils differ in composition from those from needles, which are commercially available and rich in bornyl acetate." \\ |
