We study the Banach-lie group ltaut（A） of lie triple automorphisms of a complex associative H^＊-algebra A. Some consequences about its lie algebra, the algebra of lie triple derivations of A, ltder（A）, are obtained. For a topologically simple A, in the infinite-dimensional case we have ltaut（A）0 = Aut（A） implying ltder（A） = Der（A）. In the finite-dimensional case ltaut（A）0 is a direct product of Aut（A） and a certain subgroup of lie derivations δ from A to its center, annihilating commutators.
