Extracts of 28 species of marine macroscopic algae collected from various coastal habitats of northern California were examined for antiviral activity against a broad spectrum of mammalian viruses. Ten members of Rhodophyta contained substance(s) which caused greater than a 2 log reduction in the infectivity of herpes simplex virus types 1 and 2. In addition, anti‐Coxsackie Bs virus activity was detected in extracts of Constantinea simplex Setchell. The physical and chemical properties of the… 

A Survey of Some Indian Marine Plants for Antiviral Activity

Extracts of seaweeds, seagrasses and mangroves from the southeast coast of India have been tested in vitro for antiviral activity against Newcastle disease, vaccinia, Semliki Forest,


The screening program identified the order Chroococcales as commonly producing antiviral agents, and the order Lipophilic and hydrophilic extracts from approximately 600 strains of cultured cyanophytes were examined for antiviral activity against three pathogenic viruses.

Antiviral Activity of Extracts from Marine Algae

The prophylactic but not therapeutic antiviral activity of these preparations seriously limits their potential use in human herpes simplex virus infections.

Antiviral Activity of Marine and Coastal Plants from India

Seaweeds, seagrasses, and mangroves were studied for their antiviral activity against Encephalomy-ocarditis virus and only two extracts were found to be effective with both in vitro and in vivo assay systems.

Antiviral Activity of Extracts from Marine Algaet

The prophylactic but not therapeutic antiviral activity of these preparations seriously limits their potential use in human herpes simplex virus infections.

Biological activities of seaweed extracts from British Columbia, Canada, and Korea. I. Antiviral activity

The first screening of 89 seaweeds collected from British Columbia, Canada, and Korea for antiviral activity showed a high yield of antiviral extracts, illustrating the potential of seaweeds as a resource for bioactive compounds.

Antiviral carbohydrates from marine red algae

It is possible that heparin-like sulfated polysaccharides from red algae, or fractions thereof, might be found to be low-cost, broad-spectrum antiviral agents. The prevailing view among virologists

Frequent Occurrence of HIV-Inhibitory Sulphated Polysaccharides in Marine Invertebrates

Aqueous extracts of many marine invertebrates have exhibited some activity in the National Cancer Institute's primary screen for anti-HIV cytopathicity, and it is determined that this activity is largely due to sulphated polysaccharides.

Antiviral Potential of Algae Polysaccharides Isolated from Marine Sources: A Review

This review strives for compiling previous antiviral studies of algae-derived polysaccharides and their mechanism of action towards their development as natural antiviral agents for future investigations.

Anti-HIV activity of extracts and compounds from marine algae.

Summary The effect of 4 acid polysaccharides on 2 variants of herpes virus was investigated by 3 different methods for measuring anti-viral activity. Dextran sulfate inhibited adsorption, plaque

Protective Effect of Seaweed Extracts for Chicken Embryos Infected with Influenza B or Mumps Virus

Summary 1) Polysaccharides extracted from Gelidium cartilagenium and carrageenin exerted a marked inhibitory effect on growth of influenza B virus and mumps virus in embryonated eggs but had no

This paper describes some of the studies with a very active inhibitor of viral and bacterial neuraminidases, obtained from kelp meal, that have been found to inhibit multiplication of influenza viruses in embryonated eggs.

The production of antimicrobial compounds by British marine algae I. Antibiotic-producing marine algae

Using five species of bacteria as the test organisms, 151 species of British marine algae have been screened for the production of antibiotics and it has not been possible to establish any major correlation between taxonomy and antibiotic production.

Antimicrobial agents from the sea.

Inhibition of Herpesvirus Replication by Marine Algae Extracts

Extracts from two species of marine red algae, Cryptosyphonia woodii and Farlowia mollis, specifically inhibited herpes simplex virus replication in vitro.
