We find evidence that a certain class of reaction-diffusion (RD) systems can exhibit chemical turbulence
equivalent to Nikolaevskii turbulence. We study an extended complex Ginzburg-Landau (CGL) equation derived
from this class of RD systems. First, we show numerically that the power spectrum of this CGL equation,
in the neighborhood of a codimension-two Turing?Benjamin-Feir point, is qualitatively quite similar to that of
the Nikolaevskii equation. Then, we demonstrate that the Nikolaevskii equation can in fact be obtained from
this CGL equation through a phase reduction procedure.
