The invention relates to the field of polypeptide synthesis, and specifically relates to a preparation method of terlipressin through combination of solid and liquid. According to the preparation method, Boc-Gly-OH and glycylglycine are subjected to liquid phase synthesis so as to obtain a peptide fragment (Boc-Gly-Gly-Gly-OH); at the same time, solid phase synthesis is performed to obtain a cyclic peptide segment (H-c[Cys-Tyr(OtBu)-Phe-Gln(Trt)-Asn(Trt)-Cys]-Pro-Lys(Boc)-Gly-amino resin); finally the peptide fragment and cyclic peptide segment are coupled to prepare terlipressin resin; and then the terlipressin resin is cracked, purified, and freeze-dried to obtain terlipressin. The provided technology reduces the generation of impurity peptides, improves the purity and yield of coarse peptide, simplifies the operation steps, further reduces the production cost, and can be easily applied to large scale enlarged production.
