Hi,
you can use Part for any Mathematica expression (List is only a specific case) so
I generate a similar case
sol = NDSolve[{y'[x] == y[x], y[0] == 1}, y, {x, 0, 3}]
and extract the required part
(y /. sol[[1]])[[1, 1]]
However, this is not a good practice in general, since the internal
representation of InterpolationFunction may change in the future and
arguments may change positions.
