PROBLEM TO BE SOLVED: To provide an antiviral agent having activity to animal viruses.SOLUTION: An antiviral agent having antiviral activity to animal viruses has Coccomyxa polysaccharide, as an active ingredient, extracted by: a process of performing a defatting operation, in which centrifugal separation is performed while one or a plurality of ultrasonic shaking, high-pressure homogenizing and blade agitation are combined after mixing Coccomyxa of microalgae, benzene:methanol (2:1) or volatile solvent made of ethanol, acetone and hexane, for a plurality of times; a process of adding a required amount of water after the defatting process, and heating for a required time to perform hot water extraction; and a process of concentrating and drying a liquid layer in which solid-liquid separation is performed to hot water extract by centrifugal separation. In medicine or antiseptic for animals, most lipid in the active ingredient is removed, and they have antiviral activity to at least infectious bursal disease virus of animal viruses.SELECTED DRAWING: None |
