Methods: Qualitative analysis of Semen Cassiae was performed by TLC (thin-layer-chromatograph); HPLC(high-performance liquid chromatograph) was applied to determine the quantity of Emodin in Semen Cassiae at 365nm wavelength, in which ODS-C18 volume, 0.1% methanol flow phase and PCA (perchloric acid)were used. Results: Emodin' s detection linear range is 0.05～0.8mg/L. The regression equation is Y=33.92+5391.86X, r=0.9998, average recovery is 98.70%. Conclusion: This method is simple and reliable enough to be used as the method of quality-control.
