Abstract: A method for separating a metallofullerene M@C82, comprises steps of: a) adding a Lewis acid to an extract containing the metallofullerene M@C82 to react therewith, producing a complex precipitate; b) washing the precipitate, followed by dissolving and filtering to obtain a purified metallofullerene M@C82 extract, wherein M is one or more selected from the group consisting of lanthanide metals Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Yb, and Lu; and the Lewis acid is one or more selected from the group consisting of zinc chloride, nickel chloride, copper chloride, zinc bromide, nickel bromide, and copper bromide.

Abstract: An application of a fullerene structure in the preparation of medications for treating Parkinson's disease. The fullerene structure comprises at least one of the following active ingredient groups: a fullerene, a metallofullerene, and a composition of the fullerene and the metallofullerene; an oil-soluble fullerene, an oil-soluble metallofullerene, and a composition of the oil-soluble fullerene and the oil-soluble metallofullerene; a water-soluble fullerene, a water-soluble metallofullerene, and a composition of the water-soluble fullerene and the water-soluble metallofullerene; the medicinal esters of the nine elements, or the medicinal salts of the nine elements.
