      High-performance thin-layer chromatography method for simultaneous determination of antipsychotic and medicinally important five β-carboline alkaloids
      N. SURYAKANT KADAM, A. ASHOKRAO NAIK, P. JIGNESH DOSHI, T. DAYARAM NIKAM* (*Department of Botany, Savitribai Phule Pune University, Pune, MH, India, tdnikam@unipune.ac.in, tdnikam37@gmail.com)

      J. Chromatogr. Sci. 57 (4), 312-322 (2019). Development of a method for simultaneous analysis of five antipsychotic and medicinally important β-carboline alkaloids (βCAs), namely, harmalol, harmaline, harmine, harmane and norharmane, by HPTLC on silica gel with chloroform - methanol - glacial acetic acid 39:11:1. Quantification by densitometry in fluorescence mode at 366 nm. The linearity range of standard βCAs was 25-250 ng/band, with r2 between 0.97 and 0.99. The recovery was between 83.9 and 112.4 %, repeatability of the application 0.6-2.4 %, repeatability of measurement 1.9-3.1 % and intermediate precision 0.6-11.2 %). LOD and LOQ were 4.9-6.6 and 16.5-21.9 ng/band, respectively. The method proved to be simple, cost-effective, precise, sensitive and specific for the determination of βCAs in the herbs Fagonia schweinfurthii, Peganum harmala and Tribulus terrestris, and was useful in forensic and industrial analysis and fingerprinting of various βCAs containing herbs and drug formulations.

      J. of Chromatogr. Sci. 57 (2), 149-155 (2019). Description of a selective stability indicating method for chromatographic separation of ascorbic acid (ASC), paracetamol (PAR) and guaifenesin (GUF) in presence of paracetamol toxic impurity [4-aminophenol (4-AP)] and guaifenesin related substance [impurity, (guaiacol) (GUC)] by HPTLC on silica gel with chloroform - acetone - trifluoroacetic acid 65:35:3, detection under UV 254 nm. Quantification by densitometry. The hRf values were 5 (ASC), 12 (4-AP), 24 (GUF), 41 (PAR), and 56 (GUC). The linearity was in the range of 0.4-2.4, 0.4-2.8 and 4-15 μg/band for ASC, PAR and GUF, respectively. Statistical comparison of the obtained results with those achieved by HPLC showed no significant difference. The HPTLC method proved to have advantages over HPLC, it was more sensitive and selective and permits its application in quality control of the drugs.
