 note = {Extraction of the pectic substances from a marine alga, Porphyra tenera, was attempted. The pectic substances were separated into three fractions (water-soluble, sodium hexametaphosphate-soluble, and hydrochloric acid-soluble). In the course of the separation, it was found that there are two kinds of water-soluble pectic substances one is easy to extract with water, the other is not so easily extractable. The extraction of water-soluble fraction and sodium hexametaphosphate-soluble fraction from the sample took very long period. Extraction of the pectic substances from laver was not so easy as vegetables., 6, KJ00000066170},
