The synthesis of the biological active undecapeptide substance P with the liquid-phase method (LPM) is described. The over-all-yield of the synthesis is high and the peptide shows full biological activity. The synthesis demonstrates that the modification of the liquid-phase synthesis, the cristallisation method, enables the preparation of peptides in short time with high yield and purity.
