A, a violet pigment ... The walls of the Circular Mausoleum tomb (Roman Necropolis of Carmona, Spain) exhibit an important number of violet stains of unknown origin. Analytical pyrolysis detected in the tomb walls granaticin A, a violet pigment with an isobenzochromanequinone structure, as well as in the extracts of two bacterial strains isolated from the walls. The bacterium was tentatively identified as Streptomyces sp. High performance liquid chromatography confirmed that this Streptomyces synthesized as major pigments dihydrogranaticin A, granaticin A and granaticin B. |
