Abstract: The present invention relates to a method for producing an alginic acid-folic acid conjugate, an alginic acid-folic acid conjugate produced thereby, and a pharmaceutical composition containing the same. According to the method of producing an alginic acid-folic acid conjugate using a carboxy-protecting group and a leaving group, the hydroxyl group of alginic acid forms an ester group with the carboxyl group of folic acid. Thus, the alginic acid-folic acid conjugate may clearly distinguish cancer cells from normal tissue by more effectively targeting cancer cells than a conventional alginic acid-conjugated folic acid in which the amine group of folic acid is covalently bonded to the carboxyl group of alginic acid. Accordingly, the alginic acid-folic acid conjugate may be effectively used for precise diagnosis and efficient surgical resection of cancer lesions.
