      R. ZHANG* (Zhang Rong), Y. YUE (Yue Yongde), R. HUA (Hua Rimao), W. YAN (Yan Wen) (*Recourses and Environment College of Anhui Agricultural University, Agri-food Security Key Lab of Anhui Province, No. 130, Changjiang West Road, Hefei, China; z_rong163@163.com)

      J. Planar Chromatogr. 20, 321-326 (2007). Investigation of factors affecting the separation, including the use of different stationary and mobile phases, different methods of development, humidity, and chamber saturation. TLC and HPTLC of dimethyl, diethyl, di-n-butyl, and bis-(ethylhexyl) phthalate on silica gel, prewashed with chloroform - methanol 1:1 or the mobile phase, in horizontal chambers, Vario chambers, and twin-trough chambers with 12 different mobile phases.

      Part II. Connection with RP18 and silica plates. J. Chromatogr. Sci. 46 (4), 291-297 (2008). Optimization of the one-dimensional TLC of alkaloid standards on cyano phase, RP-18W, and silica gel with various eluents containing silanol blockers (besides diluent and modifier), such as diethyl amine or ammonia. Separation of alkaloid mixtures with the most selective system (e.g. methanol - water 4:1 in the first direction and methanol - acetone - diisopropylether - diethylamine 15:15:69:1 in the second direction) with an adsorbent gradient method. Alkaloids or plant extracts of Chelidonium majus, Fumaria officinalis, or Glaucium flavum were chromatographed in the first system, the plates were connected with the plate pre-coated with various adsorbents, and partly separated fractions were transferred to the second layer and developed in a second system. Cyano - silica - RP-18W and cyano - silica - silica were used as the connected layers. The alkaloids were identified based on the Rf values of standards, and by comparison of UV spectra obtained by densitometry with a diode array detector.

Linearity was between 54 and 735 ng/spot for (1), 533 and 8531 ng/spot for (2), and 50 and 300 ng/spot for (3). The limits of detection and quantification were 12 and 21 ng/spot for (1), 240 and 426 ng/spot for (2), and 18 and 40 ng/spot for (3). Recovery was 99 % for each substance. No significant intra- and interday variation was observed. The method proved to be rapid and useful in comparison with GC and HPLC methods.

      Validation of HPTLC methods for the identification of botanicals in a cGMP environment
      E. REICH*, Anne SCHIBLI, Alison DEBATT (*CAMAG Laboratory, Sonnenmattstrasse 11, 4132 Muttenz, Switzerland; eike.reich@camag.com)

      J. AOAC Int. 91, 13-20 (2008). Comprehensive proposal for the validation of qualitative HPTLC methods. The steps of the validation process (method selection and optimization, stability, specificity, precision, and robustness) are illustrated with examples of identification methods: green tea leaf, ginseng root, eleuthero root, echinacea root, black cohosh rhizome, licorice root, kava root, milk thistle aerial parts, feverfew aerial parts, and ginger root. The validation protocol is a key element for structuring, managing and documenting the validation process. HPTLC is suitable for reliable identification of botanicals because it can provide chromatographic fingerprints that can be visualized and stored as electronic images. Reproducibility is improved if suitable instrumentation is used, a standardized HPTLC methodology is implemented, and methods have been validated.
