Effect of some factors on extraction of effectual components in cinnamon extracts

추출조건이 계피추출액의 유효성분함량에 미치는 영향

Effects of temperature, time, solvent addition ratio and number of extraction on contents of effectual components and soluble materials of cinnamon extracts were studied. All of the chemical contents of proximate composition and cinnamic acid, cinnamic aldehyde and eugenol were significantly increased as the extraction temperature increased from $20^{\circ}C$ to $80^{\circ}C$, while little change measured at $100^{\circ}C$. During ten hours of extraction at $80^{\circ}C$, more than six hours extraction showed a little increase effects the contents of cinnamic aldehyde, eugenol and proximate components. The ratio of solvents added to dried cinnamon also showed improving effects of chemical properties as the ratio increased from 5 to 40 times. Two times of extractions for 1 hour was found to be effective to recover those components.

계피추출액의 유효성분과 가용성물질의 용출량에 미치는 추출온도, 시간, 용매첨가량, 추출횟수 등의 영향을 조사하였다. 일반성분과 cinnamic acid, cinnamic aldehyde, eugenol 함량은 추출온도가 $20^{\circ}C$에서 $80^{\circ}C$로 높아짐에 따라 증가하였고 $100^{\circ}C$에서는 큰 변화가 없었다. $80^{\circ}C$에서 10시간 추출하는 동안 6시간 이상에서는 일반성분과 cinnamic acid, cinnamic aldehyde, eugenol 함량의 증가율이 낮았고 용매첨가량에 있어서는 계피중량의 $5{\sim}40$배 첨가구까지는 일반성분과 유효성분의 용출량이 증가하다가 그 이상의 용매첨가에 의해서는 완만한 증가를 보였으며 추출횟수는 $1{\sim}2$회로 하는 것이 이들 성분의 용출에 효율적이었다.
