We present an Echelle spectroscopic catalogue which until now includes more than 150 O stars observed with the 2.1 meters telescope at the Observatorio Astronómico Nacional in San Pedro Mártir, Baja California, México. Obtained spectra have a resolution of R=18,000 at 5,000 A, covering a wavelength range from 3760 A to 7400 A. For the objects in the sample a statistical study of typical stellar winds lines profiles for simple and binary stars is presented.
