Abstract

강황(Curcuma longa)으로부터 bisdemethoxycurcumin (BDMC), demethoxycurcumin (DMC) 및 curcumin의 생물 활성을 offline-ABTS 측정법과 on-line screening high-performance liquid chromatography (HPLC)-ABTS 측정법을 적용한 빠른 스크리닝을 통해 정량 및 성분 분리를 하였다. 이때, off-line-ABTS와 on-line screening HPLC-ABTS 비교는 미미한 오차를 보여주었다. Free radical scavengers in the bisdemethoxycurcumin (BDMC), demethoxycurcumin (DMC) and curcumin of turmeric (Curcuma longa) were screened, identified, quantified and isolation using coupled off-line-2,2'-azino-bis(3-ethylbenzthiazoline-6-sulphonic acid) (ABTS) and on-line screening high-performance liquid chromatography (HPLC)-ABTS assay. There was a very small margin of error between the off-line-ABTS method and the on-line screening HPLC-ABTS method.
