Observations of CO(1-0) line emission from 27 bright IRAS sources (with fluxes F100μm ≥ 500 Jy) have been made using the 13.7 m telescope of the Purple Mountain Observatory at the Qinghai Station. The authors found that all the 27 sources are associated with molecular clouds and related to the formation or early evolution of massive stars. Thirteen new CO emission spectra are presented. The properties of CO emission from this kind of sources are also discussed briefly.
