Purification of phlorotannins from Macrocystis pyrifera using macroporous resins

Food Chemistry, 2017
Phlorotannins are secondary metabolites produced by brown seaweed, which are known for their nutraceutical and pharmacological properties. The aim of this work was to determine the type of macroporous resin and the conditions of operation that improve the purification of phlorotannins extracted from brown seaweed, Macrocystis pyrifera.

Phlorotannin-Rich Ascophyllum nodosum Seaweed Extract Inhibits Influenza Infection

Viruses
Seaweed-derived compounds are a renewable resource utilised in the manufacturing and food industry. This study focuses on an enriched seaweed extract (ESE) isolated from Ascophyllum nodosum. The ESE was screened for antiviral activity by plaque reduction assays against influenza A/Puerto Rico/8/1934 H1N1 (PR8), A/X-31 H3N2 (X31) and A/England/195/2009 ...
