      Evaluation of a quantitative HPTLC method for analysis of echinacoside and cichoric acid in commercial echinacea preparations
      W.S. GEORGIAN, (S & W Microchem. Lab., 249 Boston Post Road, P.O. Box 577, East Lyme, CT 06333, USA)

      J. Planar Chromatogr. 15, 71-73 (2002). TLC of echinacoside and cichoric acid on silica gel in an aqueous, saturated potassium chloride atmosphere with ethyl acetate - formic acid - acetic acid - water 100:11:11:27. Quantification by densitometry at 330 nm. The method described has proven to be very reliable and repeatable. In addition to the ability to view the standard and samples simultaneously, the acceptable data quality, cost effectiveness, and minimal sample clean-up should enable this or a similar procedure to be regarded as suitable for the routine analysis and data reporting requirements of these compounds for preparatory and regulatory purposes. Reliable, accurate, and quantitative TLC separation.

      On-plate solid-liquid continuous extraction, a novel exhaustive technique
      V. BODIS, SZ. NYIREDY*, (*Res. Inst. for Med. Plants, Lupaszigeti ·t 4, 2011 Budakalasz, Hungary)

      Proc. Intern. Symp. on Planar Separations Plan. Chrom. 203-208 (2003). Description of the novel on-plate solid-liquid continuous extraction (SLCE) with preparative layers. The fine powdered sample to be extracted has to be introduced into a preparative layer on a 200 mm x 30 mm plate which is placed into a special device. The prepared preparative plate is covered with a glass plate, and with the help of a thick filter paper the extraction can be started with the appropriate extraction solvent.
