Abstract: Tripeptides, D-Phe-L-Pro-L-Arg-H, D-Phg-L-Pro-L-Arg-H and related compounds are purified in a process comprising 1) HPLC chromatography over an alkylsilane resin and elution with a gradient comprising an organic phase of between about 2% and about 40% of acetonitrile in an aqueous acidic phase containing an inorganic acid e.g. H.sub.2 SO.sub.4 and HCl, at a pH between about 2 and about 3, and 2) adjusting the pH of the acidic eluate with a water insoluble basic ion-exchange resin to about 4 to about 6.5. The purified peptides are useful antithrombotic agents.
