초록

건강 지향적인 사회 추세의 영향으로 건강 기능 식품의 관심과 개발이 증가되고 있다. 계피는 기능적 특성으로 인해 한약뿐만 아니라 식품 성분으로도 사용되고 있어서 본 연구에서는 추출용매와 추출방법을 달리하여 육계피 추출액의 향기 성분과 항산화활성도를 조사하였다. 육계피 추출물의 향기 성분인 coumarin, cinnamic acid, cinnamaldehyde, cinnamyl alcohol의 함량을 조사하였다. 에탄올 70%의 추출물에서 courmarin, cinnamic acid 그리고 cinnamylaldehyde의 함량은 증류수를 이용한 열수추출물과 아임계추출물에 비하여 높게 나타났다. 증류수를 이용한 아임계추출물의 courmarin, cinnamic acid, 그리고 cinnamaldehyde 함량은 열수추출물보다 높게 나타났지만, cinnamyl alcohol은 반대로 낮게 나타났다. DPPH 분석을 통한 항산화활성도 측정에서 DPPH scavenging activity는 추출물의 농도가 증가할수록 증가하였고, 70% 에탄올 추출물의 항산화활성도가 가장 크게 나타났다. FRAP 분석을 통한 항산화활성도 측정에서 70% 에탄올 추출물의 ascorbic acid 함량이 가장 크게 나타났고, 열수추출물과 아임계추출물은 유의적인 차이가 없었다(p<0.05).

The interest in and development of healthy foods and nutraceuticals have increased because of the trend for a health-oriented society. Cinnamon is used as a food ingredient as well as a herbal medicine because of its functional properties. In this study, flavoring compounds and antioxidative activities of cinnamon extracts were investigated with different extraction solvents and extraction methods. The contents of flavoring compounds such as coumarin, cinnamic acid, cinnamaldehyde, and cinnamyl alcohol were investigated. The contents of courmarin, cinnamic acid, and cinnamylaldehyde in 70% ethanol extract were higher than those in hot water and subcritical water extracts. The contents of courmarin, cinnamic acid, and cinnamaldehyde in subcritical water extract were higher than those in hot water extract, whereas the content of cinnamyl alcohol was lower. DPPH scavenging activity increased with increasing concentration of the extracts, and the 70% ethanol extract showed the highest antioxidant activity. The ascorbic acid content of the 70% ethanol extract was largest in the antioxidative activity measurement by FRAP analysis. The ascorbic acid contents of the hot water and subcritical water extracts were similar.
