Preparative HPLC를 이용한 KRF-001의 대량분리정제
Large Scale Purification of KRF-001 on the Preparative HPLC
초록
항진균물질 KRF -001의 분리정제 공정에 있어서 XAD-7 크로마토그래피, 산침전법, microfiltration 을 사용하여 crude KRF-001을 분리정재하였을 때, microfiltration 방법 이 기존의 다른 두 방법보다도 회수율이 2-3배 뒤어난 것으로 판명되었으며, 실리 카겔 크로마토그래피,
Large scale purification to get antifungal antibiotic KRF-001 of 90% purity, was investigated using preparative HPLC. Crude KRF-001 was purified by XAD-7 adsorption chromatography, acid precipitation and microfiltration. Microfiltration was the most effective isolation method of crude KRF-001. The purification methods using C18 chromatography was convenient compared with the conventional methods. Delta PAK C18 column and Bonda PAK C18 column were adapted large scale purification of KRF-001. Gradient system of prep HPLC using Delta PAK C18 column was more effective. With these conditions, final recovery of KRF-001 yielded 77%.
