Abstract

Volatile components in the needles of Abies nephrolepis (Khingan fir), a conifer native to Korea, were extracted by simultaneous distillation–extraction. Gas chromatography–mass spectrometry using two types of capillary column with different polarities (DB‐5MS and DB‐WAX) revealed that α‐pinene (23.2%) is the most abundant compound, followed by limonene (12.7%), bornyl acetate (9.9%) and β‐caryophyllene (10.8%). Aroma‐active compounds of A. nephrolepis were determined using gas chromatography–olfactometry by aroma extract dilution analysis. a‐Pinene showed the highest flavour dilution factors, ranging from 3^8^ to 3^9^ with characteristic pine aroma. (Z)‐3‐Hexenal and γ‐terpinene were also identified as important aroma‐active compounds. Copyright © 2004 John Wiley & Sons, Ltd.
