Resumen:
Six fluorescent pigments extracted from the head capsule of Ceratitis capitata were separated by two dimensional paper chromatography and further characterized by u.v./vis spectroscopy. The two main pigments had absorption maxima characteristic of the pyridine-pyrazine ring structure; this is consistent with the hypothesis that the pigments are pteridines. A time course determination of pigments during growth showed that the number of distinct pigments expressed declines with the age of the fly, thus suggesting its potential use in determining chronological (calendar) age. © 1992.
