TLC of 6 porphyrins (5,10,15,20-tetra-(4N-pyridyl)porphyrin, 5-(4-acetamidophenyl)-10,15,20-tri-(4N-pyridyl)porphyrin, 5,10-di-(4-acetamidophenyl)-15,20-di-(4N-pyridyl)porphyrin, 5,15-di-(4-acetamidophenyl)-10,20-di-(4N-pyridyl)porphyrin, 5,10,15-tri-(4-acetamidophenyl)-20-(4N-pyridyl)porphyrin, and 5,10,15,20-tetra-(acetamidophenyl)porphyrin) on RP-18 with methanol - chloroform 7:3. Visual detection. The lipophilic properties of the porphyrins were expressed by use of log PRecker, HLB (hydrophilic-lipophilic balance), and HK (determines the percentage contribution to hydrophilicity of one or more functional amido groups (-NH-CO-CH3)).

      Use of HPTLC with non-aqueous binary mobile phases for determination of selected porphyrins
      Joanna NOWAKOWSKA (University of Gdansk, Faculty of Pharmacy, Department of Physical Chemistry, Al. Gen Hallera 107, PL 80-416 Gdansk, Poland)

      J. Planar Chromatogr. 17, 388-390 (2004). HPTLC of uroporphyrins I and III, coproporphyrins I and III, and protoporphyrin on silica gel with binary mobile phases prepared by mixing pure esters, ketones, and xylenes with DMSO in proportions from 0 to 100 %. Detection under UV light at 254 nm. The separation of the porphyrins required the presence of DMSO in the mobile phase.
