      Rotation Planar Chromatography Coupled On-Line with Atmospheric Pressure Chemical Ionization Mass Spectrometry
      G. VAN BERKEL*, J. LLAVE, M. DE APADOCA, M. FORD (*Organic and Biological Mass Spectrometry Group, Chemical Sciences Division, Oak Ridge National Laboratory, Oak Ridge, Tennessee 37831-6131, USA, vanberkelgj@ornl.gov)

      Anal. Chem. 76, 479-482 (2004). Coupling of a rotation preparative layer chromatography system on-line with mass spectrometry using a simple plumbing scheme and a self-aspirating heated nebulizer probe of a corona discharge atmospheric pressure chemical ionization (APCI) source. The self-aspiration of the heated nebulizer delivers approx. 20 µL/min of the 3.0 mL/min eluate stream to the mass spectrometer, eliminating the need for an external pump in the system. The viability of the coupling is demonstrated with a three-dye mixture composed of fat red 7B, solvent green 3, and solvent blue 35 separated and eluted from a silica gel-coated rotor using toluene. The real-time characterization of the dyes eluting from the rotor is illustrated in positive ion full-scan mode. Other self-aspirating ion source systems including atmospheric pressure photoionization, electrospray ionization, and inductively coupled plasma ionization, for example, might be configured and used in a similar manner coupled to the chromatograph to expand the types of analytes that could be ionized, detected, and characterized effectively.

Detection by dipping in 10 % methanolic phosphomolybdic acid, followed by heating at 100 °C for 10 min. Evaluation under UV 366 and 254 nm. The best separation was observed on RP-18W with methanol/water mobile phases.

      Validated high-performance thin-layer chromatography method for determination of trigonelline in herbal extract and pharmaceutical dosage form
      S. CHOPRA*, F.J. AHMAD, R.K. KHAR, S.K. MOTWANI, S. MAHDI, Z. IQBAL, S. TALEGAONKAR (*Department of Pharmaceutics, Faculty of Pharmacy, Jamia Hamdard, Hamdard Nagar, New Delhi 110062, India)

      Anal. Chim. Acta 577 (1), 46-51 (2006). HPTLC of trigonelline in herbal extracts and in pharmaceutical dosage forms on silica gel with n-propanol - methanol - water 4:1:4. Quantitative determination by absorbance measurement at 269 nm. Linearity was between 100 - 1200 ng/spot (via peak area) and the correlation coefficient was 0.9991. The trigonelline content of herbal extracts quantified and estimated from the formulation was found to be well within limits (± 5 %) of the labeled content of the formulations. The method is reproducible and selective for the estimation of trigonelline by statistical analysis of the data.
