Abstract
AbstractVolatile 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 38 to 39 with characteristic pine aroma. (Z)‐3‐Hexenal and γ‐terpinene were also identified as important aroma‐active compounds. Copyright © 2004 John Wiley & Sons, Ltd.
