Adducts formation at fullerenes C60 and C70 dissolution in essential oils

It was established by the method HPLC-MS with electrospray ionization that in solutions of fullerenes C60 and C70 in some essential oils a chemical reaction occurred leading to adducts of fullerenes with unsaturated terpenes. In the course of time the quantity of the adduct in solution increased and a component originating from addition of two molecules of terpene to a molecule of fullerene is formed. This can be the reason of abnormally high solubility of light fullerenes in mixtures of terpene hydrocarbons.
