황백 껍질은 황벽나무(Phellodendron amurense)의 건조된 수피로부터 얻어진다. 이 수피는 한국의 전통 한약제로서, 설사, 황달, 무릎과 발의 통증, 요도관 및 피부 감염증에 폭넓게 사용되어 왔다. 본 연구는 황벽나무의 메탄올 추출액으로부터 항균성 화합물 분리를 위해 CPC 방법으로 효과적으로 수행하였다. 두 용매의 CPC 최적조성은 n-butanol:acetic acid:water(4:1:5 v/v/v)이었다. 이동상의 유속은 1,000 rpm 회전력에서 상승법으로 분당 3 ㎖ 속도로 전개시켰다. CPC에서 분리된 분획분은 prep-HPLC로 정제하였다. 분리된 palmatine은 1H, 13C-NMR, ESI-MS 데이터 분석으로 확인하였다.

Cortex Phellodendri (CP) is derived from the dried bark of Phellodendron amurense. It has been widely used as a drug in traditional Korea medicine for treating diarrhea, jaundice, swelling pains in the knees and feet, urinary tract infections and infections of the body surface. In this study, preparative centrifugal partition chromatography (CPC) was successfully carried out to separate antibacterial compounds from a CP methanol extract. The optimum two-phase CPC solvent system was composed of n-butanol: acetic acid: water (4:1:5 v/v/v). The flow rate of the mobile phase was 3 ㎖/min in ascending mode with rotation at 1,000 rpm. The CPC-separated fraction and purification procedures were carried out by preparatory HPLC. Palmatine weas identified by 1H, 13C-nuclear magnetic resonance and electrospray ionizationmass spectroscopy spectral data analysis.
