Cinamomum camphora (L.) Nees et Eberm. (syn. C. camphora (L.) J. Presl.) is known to exist in a number of chemotypic forms, the most common being those whose oils are rich in linalool (ho oil), camphor and 1,8-cineole. As the first two of these oils have achieved economic importance, particularly ho oil, they will be treated separately within this section.

Linalool-rich oils Bernreuther and Schreier (1991) determined that the enantiomeric ratio of linalool in ho oil was: (3R)-(-)-linalool (96.2 percent): (3S)-(+)-linalool (3.8 percent)

Linalool-rich oils of C. camphora grown in Brazil were found by Frizzo et al. (2000) to possess the following composition: α-pinene (0.01-0.08 percent) sabinene (0-0.06 percent) β-pinene (0.10-0.17 percent) myrcene (0.08-0.09 percent) limonene (0.08-0.30 percent) 1,8-cineole (0-0.15 percent) (E)-β-ocimene (0.46-0.48 percent) γ-terpinene (0-0.01 percent) linalool (93.14-95.29 percent) camphor (0.40-0.46 percent) borneol (0.11-0.20 percent) terpinen-4-ol (0-0.08 percent) α-terpineol (0-0.37 percent) p-cymen-8-ol (0-0.05 percent) isobornyl acetate (0-0.11 percent) γ-elemene (0-0.27 percent) aromadendrene (0-0.09 percent) β-caryophyllene (0.46-0.64 percent) α-humulene (0.15-0.22 percent) germacrene D (0.26-0.30 percent) bicyclogermacrene (0.12-0.26 percent) elemol (0.01-0.10 percent) (E)-nerolidol (0.09-0.11 percent) spathulenol (0-0.05 percent) safrole (0-0.03 percent)
