초록
솔잎으로부터 항균, 항산화효과 등이 입증된 바 있는 polyphenols 분리·정제를 실시하였다. 이 물질의 분리를 위한 추출용매로는 열수, EtOH, IPA를 사용하였는데, 각각의 용매에 의하여 분리된 polyphenols의 수율 및 순도는 각각 9.84, 11.61, 14.36% (w/w) 및 83.83, 82.64, 81.52%였다. 추출조건은 솔잎분말 대비 약 7배 (w/v)에 해당하는 용매를 가하고 85℃에서 6시간 동안의 처리로 추출이 가능하였다. 분리된 polyphenols의 정제는 formamide-active carbon(1:1, w/w)을 충진한 column을 통과시켜 정제한 다음 농축, 분무건조 하고, 이 분말에 식품첨가물용 n-hexane(1:2.5, w/v)을 가하여 1시간 동안 추출하여 지방성분을 추출, 제거하고 풍건하여 각각의 시제품을 얻었다.Polyphenols의 추출용매로는 열수, EtOH, IPA 중 수율과 순도를 동시에 고려할 때, 상호간의 장단점이 있었는데, 수율과 순도간에는 정의 반비례 관계가 성립하였다.
Abstract
The antimicrobial and antioxidative effect of polyphenols (PP) was proved from pine needle. This method which was seperated and purified of PP used pine needle powder as the material and assorted the solvent and then it was added the 7 times (w/v) of the material. It was extracted at 85℃ for 6 hours and was passed the column to fill with formamide-active carbon (1:1, w/v). It was concentrated and dried by sprayer, added n-hexane as the food adding material in this powder, was extracted for 1 hrs. The each sample was obtained after removing the fat component then dried. The effect of extraction solvent among the hot water, ethyl alcohol (EtOH), isopropyl alcohol (IPA) was determined depending on the yield and the purity. The relationship between the yield and purity showed the positively inverse proportion and the extraction solvent was selected as the utilization of seperation material. As the method of seperation and purification of PP was accomplished, in order to use of the new subject matter the purity enhance is expected. The application of the new subject matter as the raw material of food needs to examine actively except the functional properties of anticancerous, antimicrobial, antioxidative, antiallergic.
