The synthesis of 14C-labeled menthol was accomplished by preparation of 14C-labeled (&) pulegone. Catalytic hydrogenation and chemical reduction converted (&) pulegone to the isomeric menthols possessing 1.10 mCi total activity. Gas chromatographic separation of this material gave the relative abund
