  In this paper we consider the Bessel-Struve operator $l_\alpha$ and the
Bessel-Struve intertwining operator $\chi_\alpha$ and its dual, we define and
study the Bessel-Struve Sonine transform $S_{\alpha,\beta}$ on
$\mathcal{E}(\mathbb{R})$. We prove that $S_{\alpha,\beta}$ is a transmutation
operator from $l_\alpha$ into $l_\beta$ on $\mathcal{E}(\mathbb{R})$ and we
deduce similar result for its dual $S_{\alpha,\beta}^*$ on
$\mathcal{E}'(\mathbb{R})$. Furthermore, invoking Weyl integral transform and
the Dual Sonine transform $^tS_{\alpha,\beta}$ on $\mathcal{D}(\mathbb{R})$, we
get a relation between the Bessel-Struve transforms $\mathcal{F}^\alpha_{BS} $
and $\mathcal{F}^\beta_{BS} $.
