      TLC determination of tannins and flavonoids in extracts from some Erodium species using chemically modified stationary phases
      I. FECKA*, W. CISOWSKI, (*Dept. of Pharmacogn., Wroclaw Med. Univ., pl. Nankiera 1, 50-140 Wroclaw, Poland)

      J. Planar Chromatogr. 15, 429-432 (2002). HPTLC of natural phenolic compounds, e.g. ellagitannins, gallotannins, and flavonoid gycosides on silica gel, cellulose, DIOL-, CN- and RP-18 phases. Rutin, hyperin, isoquercitrin, luteolin 7-O-glucoside, protocatechuic acid, gallic acid, methyl gallate, and caffeic acid were used as standards. Chromatograms were developed with a variety of mobile phases. Detection under UV 254 and 366 nm and after spraying with 1% methanolic iron(III) chloride solutions, bis-diazotized sulfanilamide (tannins), or with 1% methanolic aluminium chloride (flavonoids). HPTLC of flavonoids on CN-phase with n-hexane - acetone 1:1, on DIOL-phase with diisopropyl ether - acetone - water - 98% formic acid 12:6:1:1 and on RP-18 with water - methanol - 98% - formic acid 49:50:1. TLC of tannins on silica gel with diisopropyl ether - acetone - 98% formic acid 5:4:1 and ethyl acetate - acetone - glacial acetic acid 7:2:1, on RP-18 with water - methanol - 98% formic acid 69:30:1 and on cellulose with water - glacial acetic acid 47:3.

      HPTLC and video-technology for stability tests of plant extracts
      A. SCHMID* (*Institute of Pharmacy, University of Basel, Switzerland)

      High performance thin-layer chromatographic analysis of aristolochic acid in Chinese drugs
      Anne BLATTER*, E. REICH (*CAMAG Laboratory, Sonnenmattstr. 11, 4132 Muttenz, Switzerland)

      J. Planar Chromatogr. 17, 355-359 (2004). HPTLC of aristolochic acid A, B, and C and numerous plant extracts on silica gel in a saturated twin-trough chamber using the upper phase of the mixture toluene - ethyl acetate - water - formic acid 20:10:1:1. Quantitative determination by fluorescence measurement at 366 nm after derivatization with tin(II) chloride reagent. The working range and linearity, LOD and LOQ (based on the calibration plot), and precision (n = 6), were validated with methods described by K. Ferenczi-Fodor et al., J. AOAC Int. 84 (2001) 1265-1276. The stability of the analyte during chromatography was established by two dimensional chromatography. The new method enables visual detection of the acids with certainty at very low levels (400 pg absolute of aristolochic acid A) in plant material and can therefore be used for screening Chinese drugs to ensure their safety on the basis of absence of aristolochic acid.
