Abstract: The Vector$\to $Pseudoscalar $\gamma^*$ decays $\phi \to \eta e^+ e^-$ and $\phi \to \pi^0 e^+ e^-$ have been measured based on 1.7 pb$^{-1}$ of data collected with the KLOE experiment, for extracting the branching ratios and transistion form factors. With 1.6 pb$^{-1}$ of data from the same experiment, we measure the Dalitz plot distribution of the $\eta \to \pi^+ \pi^- \pi^0$ decay. Preliminary values are given for the Dalitz plot parameters $a,b,d,f$.
