The paper presents the abundances of carbon, nitrogen, and oxygen and the carbon and oxygen isotopic ratios measured in the CN-strong giant star Mu Leo from CO and CN lines derived from a new 2-2.5 spectrum and published equivalent widths of C2 and forbidden O I lines. The relative abundances of C-12, N-14, and O-16 and the C-12/C-13 ratio suggest that Mu Leonis has undergone the first red-giant dredge-up. The CNO abundances suggest that Mu Leo is probably a metal-rich red giant that has experienced the first dredge-up. 34 references.
