The invention discloses a preparation method of oxytocin [4-Glu, 5-Asp]. The preparation method includes following steps: adopting high-performance liquid reversed phase chromatography to sequentially perform reversed phase cyclizing, reversed phase purifying and reversed phase desalting on an oxytocin [4-Glu, 5-Asp] precursor crude product solution, wherein a filler of the high-performance liquid reversed phase chromatography is silica gel C18, and an oxytocin [4-Glu, 5-Asp] precursor crude product contains two free sulfhydryl groups. A reversed phase adsorption method is creatively applied for cyclizing, purifying and desalting, so that the problems of cyclizing, purifying and desalting are solved once for all, production process is optimized, and the preparation method is suitable for industrial continuous production.
