Abstract

A process for the purification of pseudomonic acid, particularly suitable for isolating the compound when prepared by bacterial culture, comprises making a solution in an organic solvent of the acidic components of the crude preparation substantially free of the neutral components. The polarity of the organic solvent is adjusted so that the pseudomonic acid crystallises. This may be achieved either by adding a non-polar diluent such as n-heptane to the solution for example in methyl iso-butyl ketone; or by employing a di-C1-6 alkyl ether in which the acidic components dissolve and then crystallise out.
