Abies koreana E. H. Wilson - Pinaceae - 구상나무 gusang namu (Kor.), Korean fir, Korea-Tanne
Evergreen coniferous tree, up to 18m tall, native to Korea, cultivated as ornamental.
There are several cultivars, e.g. 'Silberlocke' introduced in Germany in 1986 by Gunter Horstmann.
Main components of the essential oil from the needles of A.koreana were limonene (23.4%), bornyl acetate (17.8%), α-pinene (11.1%), camphene (10.2%), and β-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%), α-pinene (23.2%), β-pinene (5.8%), terpinene-4-ol (3.8%), bornyl acetate (3.4%) and α-terpineol (3.1%). The oil exhibited broad spectrum antibacterial activity against tested organisms, including methicillin-resistant Staphylococcus aureus.

„Abies koreana essential oil (AKE) possessed anti-inflammatory and antibacterial activities against skin pathogens. In this study, AKE showed excellent antibacterial activities against drug-susceptible and -resistant Propionibacterium acnes and Staphylococcus epidermidis, which are acne-causing bacteria. In addition, AKE reduced the LPS-induced secretion of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), IL-6, NO and PGE2 in RAW 264.7 cells, indicating that it has anti-inflammatory effects.“

Major component of the fresh resinous scenting essential oil of the seeds (hydrodistilled, 3.8-8.5%) was (-)-limonene (41-72%, 95%ee).

Main compounds of the essential oil from the seeds of A.koreana (hydrodistillation, 3.8%) were (-)-limonene (53.7%, 96%ee), bornyl acetate (12.1%), α-pinene (12.1%), camphene (11.2%), β-pinene (2.0%), and borneol (1.1%). Major components of the essential oil from the cones (0.5%) were α-pinene (56.8%), (-)-limonene (13.0%, 96%ee), β-pinene (11.2%), bornyl acetate (2.9%), and camphene (2.4%).
