Abstract
Gallic acid was reported to suppress the mutagenicity and to inhibit the metabolic activation. Chitosan is a unique polysaccharide derived from chitin and is utlized as adsorbents of organic trace pollutants in environmental water sample. In this study, we have found that chitosan was suitable as a solid support to carry gallic acid. And it was examined that gallic acid could form an insoluble material when mixed with chitosan, and the solid chitosan-gallic acid complex (eco-brown) thus prepared could efficiently trap polycyclic mutagenic compounds. The adsorption of the test compounds was observed using UV/Visible spectrometry. The order of extent of removal by ecobrown was B[a]P (96.1%)>QC (83.0%)>2-AA (80.3%) >2-AF (30.3%)>PhIP (29.6%). From these results, eco-brown may be expected as a useful adsorber for several polycyclic mutagens and carcinogens.
