Extracts from the edible seaweed,Ascophyllum nodosum, inhibit lipase activityin vitro: contributions of phenolic and polysaccharide components

increased to >2500 μg DW, equivalent to >1970 μg alginate per assay. In conclusion, polysaccharides and phlorotannins may inhibit lipase in an additive fashion, with phlorotannins apparently more effective in vitro. However, interactions between these components may be important when food products containing this edible seaweed are consumed.
