On an infinite dimensional complex Hilbert space H, we consider a standard operator algebra S with an identity operator I that is closed with respect to adjoint operation. Pn(X1,X2,X3,,Xn) is set of polynomials defined under indeterminates X1,X2,,Xn by n with multiplicative Lie products with set of positive integers N. It is shown that a map Θ:SS satisfying

Θ(Pn(D1,D2,D3,,Dn))=i=1nPn(D1,,Di1,Θ(Di),Di+1,,Dn),

for any D1,D2,D3,,DnS with D1D2D3Dn=0 can be represented as d(x)+τ(x) for every xS, where d:SS is an additive derivation with another map τ:SZ(S) that vanishes on each (n1)th commutator Pn(D1,D2,D3,,Dn) with D1D2D3Dn= 0.
