Abstract

An attempt was made to derermine the volatile flavor components of Dioscorea japonica. Essential oils from roots of the samples were isolated by simultaneous steam distillation-extraction(SDE) method using diethyl ether as solvent. Concentrated samples were analyzed by gas chromatography(GC) and combined gas chromatography-mass spectrometry(GC-MS). Fifty nine volatile flavor components, including 35 hydrocarbons, 5 aldehydes, 1 ketone, 9 alcohols, 2 esters, 3 acids and 4 miscellaneous ones were confirmed in the young roots of Dioscorea japonica. Forty two components, including 23 hydrocarbons, 2 aldehydes, 7 alcohols, 1 ester and 8 acids and 1 miscellaneous one were confirmed in the roots of mature stage. ${\sigma}-3-Carene$ and dodecanoic acid were regarded as the most abundant components in young and mature roots repectively. The profile of volatile flavor components was markedly different in young and mature roots of Dioscorea japonica.

야생식용식물인 참마뿌리의 성숙도에 따른 휘발성 풍미성분을 분석하기 위해 SDE 방법으로 정유성분을 분리한 다음 GC 및 GC-MS를 이용하여 성분을 확인하였다. 어린 참마뿌리에서는 탄화수소류 35종, 알데히드류 5종, 케톤류 1종, 알콜류 9종, 에스테르류 2종, 유기산류 3종 및 기타 4종이 확인되었고, 성숙한 참마뿌리에서는 탄화수소류 23종, 알데히드류 2종, 알콜류 7종, 에스테르류 1종, 유기산류 8종 및 기타 1종이 확인되었다. 어린 참마에서 탄화수소류, 알데히드류, 알콜류 및 에스테르류의 함량이 더 많았고 풋풋한 내음이 더 강한 것으로 나타났으며 성숙한 참마에서는 고급 지방산의 함량이 상당히 많은 것으로 나타났다.
