Direct numerical simulation (DNS) of methane-air turbulent premixed flame propagating in two-dimensional homogeneous isotropic turbulence is conducted to clarify the structure of turbulent premixed flames. Detailed kinetic mechanism including 279 elementary reactions and 49 reactive species is used to simulate CH_4-air reaction in turbulence. Mole fractions of CH, N and NH are correlated with curvature and tangential strain rate at the flame elements. Flame elements compressed by turbulence and convex toward the burnt side possess high mole fractions of CH, N and NH, while streched flames possess relatively low mole fraction of these radicals.
