A novel, neutral metabolite of erythromycin was isolated from the urine of a patient treated with erythromycin ethyl succinate. After separation and purification on Sephadex LH-20 column chromatography, the structure of the metabolite was deduced from spectral data to be the propionamide of the didemethylated 6,9;9, 12-spiroketal of erythromycin A.
