[Preliminary study on TLC fingerprint of radix polygoni multiflori from different areas].
OBJECTIVE
To establish thin-layer chromatography (TLC) fingerprint of Radix Polygoni Multiflori collected from different areas.


METHODS
Quantitative analysis was carried out using TLC scanning method, two mixed solvents of petroleum ether (60-90 degrees C)-ethylacetate-formic acid (15:5:1) and chloroform-methanol-water [6.5: 2.25: 0.42, pH = 4.0 (HAc-NaAc buffer)] were employed as the mobile phase.


RESULTS
The TLC chromatograms were constituted 14 characteristic common peaks. The plots based on the height of common peaks can be conveniently used to evaluate the quality of different area samples.


CONCLUSIONS
The TLC fingerprints can be used to classify and identify Radix Polygoni Multiflori rapidly and effectively.
