Fig. 4. Sample chiral GC traces of blue spruce (B1), Norway spruce (N1), and cedar of Lebanon (C1). Compounds were identified by mass spectra (NIST library) and reference comparisons. Identified compounds are: (2) α-pinene, (3) camphene, (4) sabinene, (5) β-pinene (coeluting with β-myrcene), (7) 3-carene, (8) limonene, and (9) β-phellandrene.
