摘要
The extracts according to the present invention are characterized in that they are obtained by subjecting the alga Rissoella verrucolosa, fragmented if necessary, essentially to the following operations: - elimination of any epiphytic species; - if necessary, washing with sterile liquid and subsequent removal of the washing liquid; - extraction of substances and/or compositions contained in the alga with a solvent selected from the group comprising substances with at least one alcohol group, water, acetone, ethyl ether, hydrocarbons - aliphatic alicyclic, or mono or polynuclear aromatic-aliphatic optionally substituted with at least one halogen and/or optionally containing at least one hetero atom, and combinations thereof; - concentration of the extract obtained; and - treatment for preservation purposes. The extracts according to the invention exhibit antiviral activity, in particular against retroviruses such as for example those responsible for AIDS: HIV-1 and HIV-2.
