Abstract: Objective: To establish a new method of quality control for Lu-Gui Tincture. Methods: The 1H-NMR data of the whole composition were transformed to a matrix and analyzed by PLS-DA method using SIMCA-P software. Results: Authentic and imitated samples of Lu-Gui Tincture and its corresponding samples with shortage of one component could be distinguished by the scattering plots obviously. Conclusion: The 1H NMR-PLS-DA is a simple and useful method for the quality control of Lu-Gui Tincture.

Key words: Lu-Gui Tincture, 1H-NMR, partial least squares-discriminate analysis (PLS-DA)
