“…Although several lignans (Kim et al, 1994) and triterpenoids (Kim et al, 2001(Kim et al, , 2004Raldugin et al, 1987Raldugin et al, , 1989Raldugin et al, , 1991Roshchin et al, 1998) have been isolated from this plant in previous studies, extensive investigations for its chemical composition and biological evaluation have not yet been performed thoroughly. 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.

“…By further detailed analysis of its 2D NMR spectra and the literature data (Raldugin and Shevtsov, 1990;Raldugin et al, 1987), the structure of 5 was elucidated as methyl (25R)-3,7,23-trioxo-8,11,14-mariesiatrien-26-oate. Interestingly, compound 5 is the first example of a triterpene bearing a 8,11,14-mariesiatrien moiety.…”

“…sibirica is the source of several other lanostanes including the seco-derivative abiesolidoic acid (1 0), whose structure was established by X-ray analysis,I3 and the 24E-and 242-isomers of 3,23-dioxoIanosta-7,24-dien-26-oic acid. 14 The 242-isomer has been isolated as firmanoic acid (1 1) from A. jirma where it occurs with isofirmanoic acid (12) and the ketals firmanolide (1 3) and isofirmanolide ( 14). 15 Javeroic acid (1 5) and phellinic acid (1 6) are degraded lanostanes from the fungus Phellinus pamaceus which is found on laurisilva trees.I6 The structure of javeroic acid (15) was confirmed by X-ray analysis."…”
