Studies on the Pigment of Penicillin-producing Mold

Abstract

Penitrinic acid, C₁₅H₁₇O₅N, was isolated from the culture medium of Penicillium notatum P176. α- and β-Penitrin were obtained by the respective cleavage of peni-trinic acid by sulfuric acid and alkali. A new, nitrogen-free phenol, penitrinol, C₁₃H₁₈O₃, was obtained by the hydrogenolysis of penitrinic acid.
