Abstract
Pectin, one of the most complex polysaccharides in plant cell walls, consists of a galacturonic acid polymer as a backbone and neutral sugars chained on branches. This pectin is mainly a land-derived pectin and has been reported to have various beneficial effects such as removal of heavy metals, antioxidant activity, and anticancer activity, but pectin derived from marine algae is rarely studied and not used industrially. The aim of this study was to investigate the possibility of a new biomaterial from algal carbohydrates, a marine algae-derived pectin (i.e. marine pectin, MP), in five and nine species of micro- and macroalgae, respectively. MP extraction yields were higher in the distilled water (DW) extracts of Spirulina maxima and Ulva pertusa (yield extractions of 21.90±1.12% and 18.80± 0.97%, respectively). These results confirm that a large amount of MP was extracted by DW from marine algae, and MP is unlike the pectin derived from land plants. The MP extraction conditions were established using different solvents for each marine algae, and optimum extraction conditions exist for each species. Regarding biological activity, the MPs from Ecklonia cava and Sargassum horneri showed 99% ABTS radical scavenging activity, and the Fe2+ chelating activity of the MP from Dunaliella sp. was confirmed to be higher than those of other MPs. These results would be useful and affordable for the development and use of functional materials of DW to reduce environmental pollution and facilitate industrialization.
