A few papers have reported on the antimicrobial activity of the essential oil of A. koreana grown in Turkey (BaÌci and DiÌrak, 1996).…”

The essential oils from an alpine needle leaf of Abies koreana, which is a species native to Korea, was obtained by hydrodistillation with 0.9% (v/w) yield and analysed by GC and GC-MS. Sixty-eight constituents, accounting for more than 95.9% of the total oil composition, were identified. The main compounds with concentrations higher than 3% 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 antibacterial activity of the oil was evaluated against nine microorganisms using disc diffusion and broth microdilution methods. The essential oil exhibited some broad spectrum antibacterial activity against the tested organisms, including methicillin-resistant Staphylococcus aureus.

“…Among these species, Abies koreana Wilson (Korean fir; Korean name: Kusang namu) is a slow growing shrub or broadly pyramidal evergreen tree and widely occurs in the high mountain areas of Republic of Korea including Mt Dukyu, Mt Chiri, and Mt Halla [13]. Several lignans and triterpenoids (secocycloartenoid and two lanostane-type) have been isolated from this plant [14–16]. Previously, some authors reported the essential oil composition of A. koreana and its antimicrobial activity [12, 13, 17, 18].…”

Objectives. The present work investigates the effect of essential oil from the twigs of Abies koreana on electroencephalographic (EEG) activity of human brain in order to understand the influence of binasal and uninasal inhalations. Methods. To accomplish this study, the essential oil from the twigs of A. koreana (AEO) was isolated by steam distillation and the EEG readings were recorded using QEEG-8 system from 8 grounding electrodes according to the International 10-20 System. Results. D-Limonene (25.29%), bornyl acetate (19.31%), camphene (12.48%), α-pinene (11.88%), β-pinene (6.45%), and eudesm-7(11)-en-ol (5.38%) were the major components in the essential oil. In the EEG study, the absolute alpha (left frontal and right parietal) and absolute fast alpha (right parietal) values significantly increased during the binasal inhalation of AEO. In the uninasal inhalation, absolute beta and theta values decreased significantly, especially in the right frontal and left and right parietal regions. The results revealed that the AEO produced different EEG power spectrum changes according to the nostril difference. Conclusion. The changes in EEG values due to the inhalation of AEO may contribute to the enhancement of relaxation (binasal inhalation) and alertness/attention (right uninasal inhalation) states of brain which could be used in aromatherapy treatments.
