Chemical profiling of complex biochemical mixtures from various seaweeds

Abstract

A chemical profiling methodology is described for seaweed biomass based on comprehensive characterization of the water-soluble, water-insoluble and solid-state components. For nuclear magnetic resonance (NMR) measurements of seaweed water-insoluble components, an extraction method was developed by modification and optimization of physical pretreatments and extraction processes. Compositional variations were evaluated by NMR and attenuated total reflectance Fourier transform infrared spectroscopy, and subsequently indicated red, brown and green algae-specific profiles derived from multivariate statistical analysis.
