摘要: A process is disclosed for the solution chromatographic purification of cyclosporin A from a starting mixture containing one or more of cyclosporin A, B, C, other cyclosporin components that are more polar or more apolar than cyclosporin A, and other like contaminants, by heating the starting mixture or an evaporation residue thereof to a temperature from about 80.degree. C. to about 115.degree. C., melting the heated starting mixture, and carrying out solution chromatography of the melted material, suitably first in a 48:50:2 mixture of chloroform, dichloromethane, and ethanol, and then in a mixture of like proportions, of the solvents chloroform, ethylacetate, and ethanol.
