Abstract: There are many kinds of proteins and peptides in the bee pollen. Many of them can significantly enhance immunity. A peptide was isolated and purified from the crude bee pollen proteins which was salted out by 60%~80% ammonium sulfate. The molecular weight estimated from SDS-PAGE was 36.3 kD. The purification procedures included Superose-12 chromatography and DEAE Sepharose F.F. ion-exchange chromatography. And the peptide could significantly enhance immunity through the mice test.

Key words: bee pollen, purification, peptide
