Abstract

The Peanut sprouts have been used as food for long time in many Asian countries. Among them, resveratrol have bioactivity effects as antioxidant and anticancer. In this work, resveratrol was extracted from peanut sprouts by dipping(extraction time 3h, $25^{\circ}C$) method. And extraction efficiency and amount was identified using on-line screening HPLC-ABTS. From the experimental results, it is evident that the amount of resveratrol($0.310-0.346{\mu}g/mL$) by 50% aqueous EtOH was higher than any 100% water and EtOH composition. Also, the 100% water extracts sample was low yield 2.040-2.145%. The shown results can be applied as sources for pharmaceuticals and functional material.

땅콩새싹은 많은 아시아 국가에서 오랜 시간 동안 식품으로 사용되어왔다. 그중에서 resveratrol은 항산화 및 항암 등의 생리 활성 효과가 있다. 본 연구는 resveratrol은 침적방법(추출시간 3h, $25^{\circ}C$)을 이용하여 추출하였다. 그리고 on-line screening HPLC-ABTS을 사용하여 추출 효율 및 함량을 확인 하였다. 추출액은 상업용 C18 역상 고성능액체 크로마토그래피에 의한 이동상으로 물과 아세토나이트릴을 사용하여 선형기울기용매법으로 분리 분석을 하였다. 유속은 1.0mL/min, 주입부피는 $10{\mu}L$, 컬럼오븐 온도 $40^{\circ}C$, 파장 320nm에서 수행되었다. 실험결과, 50% 에탄올에서 resveratrol 함량이($0.310-0.346{\mu}g/mL$) 100% 물과 에탄올 조성보다 높았다. 또한 100% 물 추출물의 수율은 2.040-2.145%로 낮았다. 위의 결과 on-line HPLC-ABTS 분석은 식물추출물의 생물활성을 빠르고 특화된 강력한 기술이 될 수 있음을 보여주었다. 이것은 제약 및 기능성 소재로서의 응용 가능성을 나타내었다.
