      Efficient and sensitive method for quantitative analysis of 6-gingerol in marketed Ayurvedic formulation
      K.K. ROUT*, S.K. MISHRA (*Pharmacognosy and Phytochemistry Division, University Department of Pharmaceutical Sciences, Utkal University, Vani Vihar, Bhubaneswar 751004, Orissa, India; kd_rout@yahoo.co.in)

      J. Planar Chromatogr. 22, 127-131 (2009). HPTLC of 6-gingerol, extracts of Suprabha and market samples of ginger on silica gel (prewashed with methanol) with n-hexane - acetone 18:7 in a twin trough chamber saturated for 4 min at 20 +/- 4 °C and 36 +/- 3 % relative humidity. Quantitative determination by absorbance measurement at 286 nm. The limit of detection and quantification was 40 and 150 ng/band, respectively.

      A comparative study on several algorithms for denoising of thin-layer densitograms
      L. KOMSTA (Department of Medicinal Chemistry, Medical University of Lublin, Jaczewskiego 4, 20-090 Lublin, Poland)

      Anal. Chim. Acta 641 (1-2), 52-58 (2009). Comparison of classical filtering techniques (Savitzky–Golay, Adaptive Degree Polynomial Filter, Fourier denoising, Butterworth and Chebyshev IIR filters) and wavelet shrinkage (31 mother wavelets, 3 thresholding techniques and 11 decomposition levels) with the original noisy signal and a reference signal which was denoised experimentally by averaging 64 measurements. The best similarity to the reference signal was obtained with filters, however the signal was slightly oversmoothed. The wavelet shrinkage method gave less denoised signals. There was a significant influence of the thresholding technique and decomposition level, and best conditions were at level 2 or 3 and soft thresholding), whereas changing of the mother wavelet almost did not change the result. The presented results can be used as general recommendations for denoising densitometric fingerprints before applying further chemometric algorithms. The best choices were: Savitzky–Golay filter of appropriate window width (optimized against autocorrelation) or wavelet shrinkage with Haar wavelet, soft thresholding and high decomposition level.

      Determination of available lysine by planar chromatography
      M. VEGA*, M. ARANDA (*University of Concepcion, Faculty of Pharmacy, Department of Food Science, Nutrition and Dietetic, Barrio Universitario s/n Casilla 237, PO 403-0249 Concepcion, Chile; mveha@udec.cl)

      J. AOAC Int. 92, 699-702 (2009). HPTLC of a dinitrophenyl-lysine derivative (produced by incubation with 1-fluoro-2,4-dinitrobenzene and hydolyzation with hydrochloric acid) on silica gel (prewashed with methanol) with n-propanol - 25 % ammonia 7:3 in a twin trough chamber. Quantitative determination by absorbance measurement at 360 nm. The method was linear (r2 = 0.9991) in the range from 12.5 to 125.0 ng/band. Repeatability (%RSD) and intermediate precision (%RSD) in matrix were 0.8 % and 3.6 %, respectively. Recoveries of spiked samples at two levels ranged from 72 to 85 % with RSD from 3 to 8%. This method is a reliable, high throughput and low cost analytical method for the salmon feed industry.
