Endomorphin-2 was synthesized successfully from C-terminal to N-terminal according to the a-mino acids sequence with the raw material of Fmoc-amino acids and Rink Amide resin as the vector. DIC/HOBt as the coupling reagent. The crude peptide of endomorphin-2 was obtained by cracking by TFA from the resin,the purity of crude product was 98. 5%. Then the target product of endomorphin-2 was achieved after purification and turning salt by preparative reversed-phase high performance liquid chromatography. The purity of refined peptide was more than 99. 0%,and the yield was reach 80%.
