We present and analyze infrared spectra of the supergiant VR 5–7, in the Quintuplet cluster 30 pc from the Galactic center. Within the uncertainties, the [C/H], [N/H], and [O/H] abundances in this star are equal to those of α Ori, a star which exhibits mixing of CNO processed elements, but are distinct from the abundance patterns in IRS 7.
