Several attempts have been made in recent years to fully characterize phlorotannin-rich extracts. Nevertheless, this remains a challenging quest, not only because of seaweed complex chemical composition, but also due to the diverse structural assemblage within phlorotannin molecules (i.e., type of linkage, modification site, and number of additional hydroxyl groups). In this work, 22 phlorotannins...
NO scavenging (r=−0.6363; p=0.0108). The anti-inflammatory capacity of phlorotannin extracts was further evaluated using RAW 264.7 macrophages stimulated with bacterial lipopolysaccharide, as model of inflammation. The extracts studied were not toxic at the tested concentrations (31.25–500μg/mL). F. vesiculosus from wild origin was the most effective in reducing NO in cell culture medium (IC25=56...
