How to identify equations

Hi there

Is there a Mathematica function which one can use to identify another given
function
within an equation. I would like to do, for instance, the following:

F[x] = ...function..... (this is given)
DF[x] = D[F[x],x]      (derivative of F]

I now want to simplify DF[x] and identify the original function F therein and
then let Mathematica write out DF as a function of F instead of using the
defined F.

Can this be done

Thanks for the help
