Discovery of fluorescent substances in the yellow organ of Caecospaeroma burgundum Dollfus, Isopod Crustacean of underground waters.
Descimon Henry, Marvillet Claude
Abstract:
Chromatographic analysis of the yellow organs of the fresh-water Isopod Crustacean Caecosphaeroma burgundum Dollfus revealed, through observation of the chromatograms in ultraviolet light, the occurrence of both absorbing and fluorescent substances. Among the latter, only isoxanthopterin has been identified. The yellow pigment, which probably has a pteridine nucleus, could not be identified as a known compound and will be the object of later investigations.
