Endohedral metallofullerenes, Ca@C60 and Sr@C60, prepared by the arc-heating of the graphite rods containing CaO and SrO, respectively, have been extracted with aniline under the air atmosphere. The laser desorption time-of-flight (LD-TOF) mass spectra for the extracted solutions exhibit intense peaks due to M@C60+ (M: Ca and Sr) and C60+ with weak peaks due to the other hallow fullerenes and metallofullerenes.
