Spectroscopic characterization of phycobiliprotein (PBP) isolated fromSpirulina platensis indicated that it had a molecular formula of C33H40N4O6 with molecular ion peak at m/e 586. The PBP was rich in aliphatic and acidic amino acid residues. The specific ultra-violet absorbance, infrared transmittance, specific absorbance coefficient, nuclear magnetic resonance and mass spectral analysis revealed thatS. platensis PBP was composed mainly of C-phycocyanin and allophycocyanin.

Keywords: amino acids; infrared transmittance; NMR; UV absorbance
