A preparative high-performance liquid chromatography was examined for the isolation of higher fullerenes from CS2 extracts of the carbon soot produced by arc heating of graphite in inert atmosphere. At least eight all-carbon compounds C60, C70, C76, C78, C82, C84, C90 and C96 were confirmed as a "stable fullerene". C82 and C96 are new members of fullerene family which have not been reported so far. The presence of stable C82 seems to be closely related with the recent success of macroscopic quantities of production of LaC82 reported by Smalley's group.
