The invention relates to a plant extract obtained by a single-phase extraction method, by means of a solvent and/or a mixture of solvents of plant origin, containing characterised and chemically defined constituents. Said plant extract is characterised in that it is free of polyphenol, anthocyan and/or tannin, and comprises a fraction of lipophile-type components and/or a fraction of polar-type components. The invention also relates to an extraction method which enables an inventive extract to be obtained, said method being a single-phase extraction method characterised in that it comprises the following steps: a plant material is brought into contact with a solvent and/or a mixture of solvents of plant origin, containing characterised and chemically defined constituents; the plant material is eliminated; and the solvent and/or mixture of solvents is partially or completely eliminated. Said solvent and/or at least one of the constituents of the mixture of solvents is selected from the group of terpenic solvents having a purity which is at least equal to 98% and being depleted of peroxides.
