Twelve tryptic peptides as well as free arginine were isolated from the performic acid-oxidized Ala chain of ricin D by gel filtration on Sephadex G-25 and Dowex 1×2 column chromatography followed by paper chromatography. Total number of the amino acid residues in these peptides accounted for 90 out of 263 residues in the Ala chain of ricin D. The amino acid sequences of nine peptides were determined by manual Ed man degradation.
