Abstract
The objective of this experiment is to understand the volatile composition of the essential oil from flower of daisy fleabane (Erigeron annuus (L.) Pers.). The essential oil was extracted using a steam distillation apparatus, collected by solid-phase microextraction, and analyzed by GC-MS. The yield of the essential oil was 0.22% and the fragrance was herbal, minty, oily and fruity. Twenty-eight constituents were identified from the essential oil: 16 hydrocarbons, 5 alcohols, 5 ethers, 1 nitrogen-containing compound and 1 acid. Major volatile compounds were 1H-cyclopenta[1,3] cyclopropa[1,2]benzene (32.9%), methyl-(Z)-dec-2-en-4,6-diynoate (16.1%), 3,7-dimethyl-(Z)-1,3,6- octatriene (15.1%), 1,2,3,4,4a,5,6,8a-octahydronaphthalene (6.6%), and 1-ethenyl-1-methyl-2,4-bis (1-methylethenyl)-[1S-(1a,2b,4b)]-cyclohexane (6.5%). The overall data showed that floral essential oil of daisy fleabane had unique chemicals with unique fragrance, suggesting the essential oil could be used as a raw material for the development of new fragrances.
본 연구의 목적은 개망초(Erigeron annuus (L.) Pers.) 꽃으로부터 얻은 정유에 함유되어 있는 화학성분을 구명하는데 있다. 수증기 정유장치로부터 얻은 정유를 solid-phase microextraction 방법을 이용하여 추출한 다음 GC-MS로 분석하였다. 개망초 꽃에 0.22% 함유된 정유의 향취는 herbal, minty, oily, fruity 하였다. 개망초 꽃 정유는 총 28개의 화학성분으로 구성되었는데, 이를 성분별로 구분하면 탄수화물이 16개, 알코올이 5개, 에테르가 5개, 질소화합물이 1개, 산이 1개이었다. 정유의 함유된 주된 화합물은 1H-cyclopenta[1,3]cyclopropa[1,2]benzene(32.9%), methyl (Z)-dec-2-en-4,6-diynoate(16.1%), 3,7-dimethyl- (Z)-1,3,6-octatriene(15.1%), 1,2,3,4,4a,5,6,8a-octahydro- naphthalene(6.6%), and 1-ethenyl-1-methyl-2,4-bis(1- methylethenyl)-[1s-(1a,2b,4b)]-cyclohexane(6.5%)이었다. 개망초 꽃으로부터 추출된 정유 또는 그 정유에 함유되어 있는 방향성 화합물은 매우 독특한 향취를 갖고 있어서 향후 다양한 향료제품개발에 활용될 수 있을 것이라 판단된다.
