dc.description.abstractMicroemulsion thin layer chromatography (ME-TLC) has been developed for the fingerprinting of aqueous extract of licorice (Glycyrrhiza spp.). The separation conditions and operational processes of the method have been optimized, and its chromatographic characteristics compared with conventional TLC. The ME-TLC system is easier to operate, and with higher resolution and better reproducibility than the conventional TLC. The separation mechanism and retention behavior of ME-TLC are found to differ significantly from conventional TLC. The technique has been applied to the analysis of different licorice species including G. uralensis, G. glabra and G. inflata; and to monitor the dynamic accumulation of active ingredients in licorice plant harvested at different times during its growing cycle in a Good Agriculture Practice (GAP) research farm. Results show that without post-chromatographic derivatization, the ME-TLC fingerprinting images of different species appear as clear, well resolved bands and with strong intensities to reveal distinctively different compositional features of the samples. The technique has also been applied successfully to monitor the dynamic accumulation of active components in licorice plant as a function of growing time in an experimental licorice farm. The study demonstrates the potential of ME-TLC technique as a rapid fingerprinting tool for the authentication and quality assessment of licorice as well as other herbs.
