Summary Using rather simple and mild extraction and separation methods, three ovine pineal fractions (XM300 R-PP7.2, PP7.2′ and PP7.2S) were obtained, which contain peptidic/proteic substances and which show fluorescence characteristics of indoles. The ovine fractions were compared with the bovine pineal E 5-fraction. The ovine fractions are chemically sensitive to normal laboratory light and stable in red light (λ〉600nm). Immunologically, these fractions and the bovine E 5 fraction are stable. From the results of radioimmunological experiments it was concluded that the bovine pineal E 5 fraction as well as the ovine pineal fraction XM300R-PP7.2 and PP7.2S may contain (a) peptide(s) ending by the same carboxy terminal tripeptide Pro-Arg-Gly(NH2).
