[D(--)alpha-aminobenzylpenicilline and amino acid pattern in urine (author's transl)].

Three cases of patients with D(--)alpha-aminobenzylpenicillinuria are reported. On the quantitative, urinary amino acid chromatogram we found a high ninhydrinpostitive peak between the xi-aminocaproic acid and the arginine peak. Column chromatographic and thin-layer chromatographic studies with test substances permitted to identify the unknown peak as D(--)alpha-aminobenzylpenicillin.
