Objective: To develop a method that can well evaluate the quality of Xiatianwu.
Methods: Methods are researched and discussed to construct the TLC-FP (thin-layer chromatography finger-print) of Xiatianwu to evaluate its quality.
Results: The areas of six evident peaks in the thin-layer chromatography of Xiatianwu are compared with the area of dl-tetrahydropalmatine peak companied with them in the same chromatography. The Rr of every peak and its relative area were acquired to evaluate the quality of Xiatianwu and identify it.
Conclusion: The TLC-fingerprint of Xiatianwu can well evaluate the quality of Xiatianwu.
