Resumen:
We present some results of a spectroscopic survey of early-type multiple stars. We detected new binary and multiple subsystems and we obtained orbital parameters of catalogued binaries without previous data. In this contribution we describe the orbital analysis of two binary subsystems without published periods and two SB2s previously catalogued as single-lined spectroscopic binaries. Also we report the discovery of seven new subsystems. Three of them are double-lined spectroscopic binaries.
