摘要：

A standard humic acid extraction procedure has been used to isolate dark brown organic residues from samples of the macroscopic marine brown alga Pilayella littoralis. The residues are insoluble in water, but soluble at high pH, and are similar in elemental composition, ash content, UV-visible, IR, PMR and X-Ray fluorescence spectra, X-Ray diffractograms and scanning electron micrographs to residues of a humic acid isolated from municipal compost. These results indicate that Pilayella produces humic acids.
