      Phytochem. Anal. 20, 19-23 (2009). TLC of curcumin (1), demethoxycurcumin (2), and bisdemethoxycurcumin (3) from the rhizomes of Curcuma longa on silica gel with hexane – chloroform – methanol 10:10:1 as mobile phase. Quantitative determination by recording the chromatogram using a digital scanner and analyzing the density of the TLC spot with the Scion Image software. The hRf values of (1), (2), and (3) were 42, 25, and 18, respectively. Selectivity regarding matrix was given. Linearity was between 0.375 and 6 µg/spot for all curcuminoids. The intermediate precision of the method was satisfactory. Recovery was 101.9 % for (1), 104.8 % for (2), and 101.5 % for (3). The limits of detection and quantification were 43 and 143 ng/spot for (1), 69 and 230 ng/spot for (2), and 73 and 242 ng/spot for (3). The method was compared with an official densitometric method, and the analytical results were not significantly different.

      A new method for the isolation of betalaines by HPTLC
      M. MORENO*, A. VILORIA, D. HIDALGO (*Simon Rodriguez University, Valencia, Venezuela, morenoalvarez@cantv.net)

      Rev. Fac. Agron. 21, 155-160 (2004). HPTLC of betaxantin and betacyanin in the roots of Beta vulgaris on cellulose in two one-dimensional developments with 1) isopropanol – ethanol – water – acetic acid 6:7:6:1 and 2) isopropanol – ethanol – water – acetic acid 11:4:4:1. Qualitative identification under UV light. Betaxantin and betacyanin showed maximum absorbances at 537 and 465 nm, respectively. The hRf values of betaxantin and betacyanin were 22 and 34, respectively.

      Evaluation of traditional Chinese herbal medicine
      R. TIAN (Tian RunTao)*,P. XIE (Xie PeiShan), H. LIU (Liu HePing) (*Chromap Institute of Herbal Medicine Research, Zhuhai, Guangdong, China)

      J. Chromatogr. A 1216 (11), 2150-2155 (2009). Chaihu roots (Bupleuri radix), roots of Bupleurum chinense and Bupleurum scorzonerifolium are monographed in the Chinese Pharmacopoeia. Evaluation of the quality of 33 lots of authenticated Chaihu samples versus 31 lots of commercial samples by HPLC-ELSD and HPTLC analysis of the principal bioactive components (saikosaponins). Data acquired from HPLC fingerprints and HPTLC fluorescent images was analyzed by chemometrics for similarity and pattern recognition, including artificial neural networks, k-nearest neighbor (k-NN) and an expert’s panel. The k-NN classifier showed good performance with sufficient flexibility for processing HPTLC fingerprint images. These images were otherwise not easily dealt with by other algorithms due to the shift of hRf values and varying hue/saturation of the band colors between different TLC plates. The two chromatographic fingerprint methods are complementary measures for quality control. Chaihu roots from different species of the genus Bupleurum could readily be distinguished from each other. Commercial samples of Chaihu can easily be classified by investigating the content of major saikosaponins.

Quantitative determination by absorbance measurement at 206 nm. Derivatization by dipping in Fast Blue B solution for 5 s. The hRf value of delta-9-tetrahydrocannabinol was 47 and selectivity regarding matrix was given. Linearity was given between 50 and 500 ng/zone. The limit of quantification and detection was 50 and 10 ng/zone, respectively. The intra- and inter-day repeatability (%RSD, n = 9) were not higher than 5.0 %. Recovery was 85.8 % for delta-9-tetrahydrocannabinol in decarboxylated Cannabis samples. The method was shown to be comparable within a small degree of error (0.5 %) to results from a validated HPLC method.
