Abstract
Let $\mathcal{A}$ be a unital complex $\ast $-algebra having a nontrivial projection. In this paper, we proved that every $\ast $-derivation-type map $\Phi :\mathcal{A}\rightarrow \mathcal{A}$ on sum of triple products $\alpha _{1} abc+\alpha _{2} a^{*}cb^{*}+\alpha _{3} ba^{*}c +\alpha _{4} cab^{*}+\alpha _{5} bca+\alpha _{6} cb^{*}a^{*},$ where the scalars $\{\alpha _{k}\}_{k=1}^{6}$ are rational numbers satisfying some conditions, is an additive $\ast $-derivation. Some applications of the results obtained are also presented.
