Abstract

$Coptis$ $chinensis$ Franch rhizome is one of the important traditional Korea medicines with anti-inflammatory, anti-bacterial, anti-hypertensive and anti-cancer properties. The methanol extract of rhizome from the $Coptis$ $chinensis$ rhizome was purified by using preparative centrifugal partition chromatography (CPC) and HPLC method. The optimum two-phase CPC solvent system was composed of n-butanol:acetic acid:water at a ratio of 4:1:5. Berberine (16.8 mg) was successfully isolated by CPC and HPLC. The chemical structure of the compound was identified by (1 H)$^1H$, $^{13}C$-NMR and ESI-MS spectral data analysis.

황련은 염증, 항균, 고혈압 및 항암 작용을 지닌 중요한 전통 한약재이다. 황련 뿌리 메탄올 추출성분은 CPC와 HPLC 방법으로 정제하였다. CPC의 최적 용매 조건은 n-butanol:acetic acid:water(4:1:5)이었다. Berberine(16.8 mg)은 CPC와 HPLC 방법에 의하여 효과적으로 분리하였다. 이 물질의 화학적 구조는 $^1H$, $^{13}C$-NMR과 ESI-MS 데이터 분석에 의하여 확인되었다.
