      An image analysis system for thin-layer chromatography quantification and its validation
      T. TANG (Tang Tie-Xin )*, W. HONG (Hong Wu) (*Center for Medicinal Plants Research, South China Agricultural University, Guangzhou 510642, China)

      J. Chromatogr. Sci. 46 (6), 560-564 (2008). Quantitative TLC is performed with a digital imaging system with simple equipment and software. The method was used for the quantitative assay of cichoric acid in Echinacea purpurea. TLC on polyamide phase with chloroform - methanol - formic acid - water 3:6:1:1. Detection by spraying with 3 % aqueous aluminum chloride solution. Images of chromatograms were acquired with a standard digital camera under a UV lamp at 365 nm in a dark room. The three-dimensional grayscale digital image dataset (x, y, gray) was reduced to a two-dimensional dataset (distance, accumulative gray) and then plotted as a curve. For quantification the area under the curve (corresponding to cichoric acid) was integrated.
