Main components of the essential oil, collected by steam distillation of the exudates from D.aromatica, were β-caryophyllene (21-37%), α-caryophyllene (8-16%), α-pinene (10-36%), terpinen-4-ol (5-10%) and α-terpineol (3-7%). Borneol was detected in the essential oil of D. aromatica at 0.74%. "This finding was different from other studies. Huang and Lu reviewed that the exudates or essential oil of D. aromatica comprised of borneol, α-caryophyllene, β-elemene, β-caryophyllene, asiatic acid, dryobalanone, erythrodiol and hydroxy-dammarenone II." \\
