dc.description.abstract Pressurized liquid extraction (PLE), an environmentally friendly technique, has been used to obtain antiviral compounds from microalgae commonly used as carotenoids sources: Haematococcus pluvialis and Dunaliella salina. The antiviral properties of PLE extracts (hexane, ethanol and water) were evaluated against herpes simplex virus type 1 (HSV-1) at different stages during viral infection. Pre-treatment of Vero cells with 75 µg mL-1 of H. pluvialis ethanol extract inhibited virus infection by approx. 85%, whereas the same concentration of water and hexane extracts reduced the virus infectivity 75% and 50% respectively. D. salina extracts were less effective than H. pluvialis extracts and presented a different behaviour, since water and ethanol extracts produced a similar virus inhibition (65%). Moreover, H. pluvialis ethanol extract was also the most effective against HSV-1 intracellular replication. The antiviral activity of water PLE extracts was found to correlate with polysaccharides, since the polysaccharide-rich fraction isolated from these extracts showed higher antiviral activity than the original water extracts. A GC-MS characterization of the H. pluvialis ethanol extract showed the antiviral activity of this extract could be partially related with the presence of short chain fatty acids, although other compounds could be involved in this activity; meanwhile, in the case of D. salina ethanol extract other compounds seemed to be implied, such as: β-ionone, neophytadiene, phytol, palmitic acid and α-linolenic acid. Results demonstrated the use of PLE allows obtaining antiviral compounds from microalgae used as carotenoids sources, which gives both microalgae biomass an added value. en_US
