  The radiative decay of $f_1(1285)$ to vector mesons $\rho$ and $\phi$ is
calculated in a non-relativistic approach. The results obtained are compared to
experimental data to estimate the glue content of $f_1$. We find a small or
nonexistent glue content when our results are compared to the PDG data. However
a large glue content for $f_1(1285)$ was found when we compared our results to
the CLAS data.
