Analytical, diagnostic and therapeutic context of Pyrrole-2,3,5-tricarboxylic acid

  • The degradation products, PTCA and AHP, were determined by high-performance liquid chromatography [8].
  • The PTCA values obtained by means of HPLC were correlated with the near infrared spectrum of the respective samples [9].
  • For epidemiological studies, chromatographic methods of determining pyrrole-2,3,5-tricarboxylic acid (PTCA; the principal marker of eumelanin) are long, laborious and unsuitable for screening large populations [9].
  • A correlation between the PTCA values obtained by means of HPLC and the PTCA values obtained from an analysis of the spectra was obtained using the principal component regression (PCR) algorithm [9].
