곰취(Ligularia fischeri)와 한대리곰취(Ligularia fischeri var. spicifoprmis) 정유의 향취 및 향기성분 비교

국문 초록 (Abstract)

본 연구의 목적은 곰취(Ligularia fischeri)와 한대리곰취(Ligularia fischeri var. spicifoprmis) 정유의 향취 및 화학성분을 비교하는데 있다. 곰취와 한대리곰취의 정유 함량은 각각 0.12%와 0.04%였으며, 역치수준은 각각 0.01%와 0.1%였다. 향수개발전문가에 의해 평가된 곰취 정유의 향취는 citrus, coniferous, green, oily, smoky, wet하였던 반면 한대리곰취 정유의 향취는 balsam, earthy, oily, wet하여 매우 상이하였다. 곰취 정유에는 총 19종의 화학성분이 검출되었는데 탄화수소가 14종(75%), 알코올이 4종(20%), 아세테이트가 1종(5%)이었으며, 주된 화학성분은 L-β-pinene(36.02%), D-limonene(25.64%), α-pinene(24.85%), β-phellandrene(5.39%), 3-carene(3.77%), α-phellandrene(2.05%)이었다. 한대리곰취 정유에는 총 25종의 화학성분이 검출되었는데 탄화수소 17종(68%), 알코올 4종(16%), 아세테이트 3종(12%), 질소화합물 1종(4%)이었으며, 주된 화학성분은 D-limonene(39.80%), L-β-pinene(35.43%) α-pinene(11.94%), 3-carene(3.70%), β-cubebene(3.51%), β-phellandrene(2.38%)이었다. 한대리곰취 정유에서는 ρ-cymene, γ-muurolene, γ-cadinene, germacrene D, ingol 12-acetate, butyl 9,12,15-octadecatriene과 nimorazole이 미량 검출되었으나, 곰취 정유에서는 이러한 화학성분들이 검출되지 않았다. 본 연구의 결과 각각 독특한 향취를 갖는 곰취와 한대리곰취 정유는 향장산업제품 개발을 위한 소재로 활용될 수 있을 것이라 판단된다.

This study was conducted to compare fragrance and volatile chemicals of essential oils in Gom-chewi (Ligularia fischeri) and Handaeri Gom-chewi (Ligularia fischeri var. spicifoprmis). Essential oils were extracted by steam distillation of leaves of Gom-chewi (GC) and Handaeri Gom-chewi (HGC), after which samples were collected by solid-phase micro extraction and the compositions of the essential oils were analyzed by gas chromatography- mass spectrometry (GC-MS). The yields of the essential oils in GC and HGC were 0.12% and 0.04%, respectively, and the threshold levels of the essential oils in GC and HGC were 0.01% and 0.1%, respectively. There were 19 constituents of the essential oil of Gom-chewi: 14 carbohydrates, 4 alcohols, and 1 acetate, and the major constituents were L-β-pinene (36.02%), D-limonene (25.64%), α-pinene (24.85%) and β-phellandrene (5.39%). In the essential oil of HGC, 25 constituents were identified: 17 carbohydrates, 4 alcohols, 3 acetates, and 1 N-containing compound, and the major constituents of HGC were D-limonene (39.74%), L-β-pinene (35.43%) and α-pinene (11.94%). The minor constituents of HGC were ρ-cymene, γ-muurolene, γ-cadinene, germacrene D, ingol 12-acetate and butyl 9,12,15-octadecatriene and nimorazole were not identified in the GC essential oil. Overall, the results showed that the fragrance and chemical compositions of essential oils in GC and HGC differed, suggesting that both essential oils could be used for the development of perfumery products.
