Chemical compositions such as total sugar, sulfate/total sugar, protein and 3,6-anhydrogalactose content of porphyran extracted from commercial laver, discolored laver and laver waste were measured. The total sugar contents of commercial laver, discolored laver and laver waste showed 54.5%, 45.7% and 56.2%, respectively. The total sugar of the commercial laver and laver waste were showed almost similar portion although that of discolored laver showed relatively lower level. The sulfate/total sugar contents showed 17.6%, 13.9% and 17.3%, and 3,6-anhydrogalactose contents showed 13.8%, 9.1% and 13.9% in commercial laver, discoloredlaver and laver waste respectively.
