    • A process for purifying cyclic lipopeptide compounds or salts thereof comprising the steps of: (1) charging a crude compound of Formula I onto a macroporous adsorption resin; (2) washing the macroporous adsorption resin using water, an organic solvent or a mixed solution of an organic solvent and water as a washing liquid; and (3) eluting the compound of Formula I from the macroporous adsorption resin using water, an organic solvent or a mixed solution of an organic solvent and water as an eluent. The purification method has the advantages of using a small amount of organic solvents, using no silica gel, and causing little damage to the environment; the purity of the collected compound of formula I is also improved as compared with the methods previously disclosed.
    • 一种用于纯化环状脂肽化合物或其盐的方法,包括以下步骤:(1)将式I的粗制化合物装入大孔吸附树脂中; (2)使用水,有机溶剂或有机溶剂和水的混合溶液作为洗涤液洗涤大孔吸附树脂; 和(3)使用水,有机溶剂或有机溶剂和水的混合溶液作为洗脱剂,从大孔吸附树脂中洗脱式I化合物。 净化方法的优点是使用少量的有机溶剂,不使用硅胶,对环境几乎没有损害; 与以前公开的方法相比,所收集的式I化合物的纯度也得到改善。
