Main components of the essential oil from the needles of A.koreana were limonene (23.4%), bornyl acetate (17.8%), alpha-pinene (11.1%), camphene (10.2%), and beta-himachalene (4.1%). The essential oil exhibited high antimicrobial activity against the tested organisms Escherichia coli, Staphylococcus epidermidis and Candida albicans.

Main compounds of the essential oil from the needles of A.koreana (hydrodistillation, 0.9%) were borneol (27.9%), alpha-pinene (23.2%), beta-pinene (5.8%), terpinene-4-ol (3.8%), bornyl acetate (3.4%) and alpha-terpineol (3.1%). The oil exhibited broad spectrum antibacterial activity against tested organisms, including methicillin-resistant Staphylococcus aureus.

The essential oil is known to help respiratory system and have easing and soothing effect for muscle. Bornyl acetate (30.3%), camphene (19.8%), 3-carene (13.8%), tricyclene (12.9%), limonene (7.5%), α-pinene (2.8%), caryophyllene (2.18%), β-phellandrene (2.1%), borneol (1.7%), bicyclo[2.2.1]hept-2-ene,2,3-dimethyl (1.6%) and α-terpinene (1.2%) were the major components. The oil exhibited antibacterial activity against Staphylococcus aureus, Streptococcus mutans, Listeria monocytogenes, Acinetobacter baumannii, Escherichia coli, and Vibrio parahaemolyticcus.
