Abstract: OBJECTIVE: To establish the quality standard for Baiban paste. METHODS: The two component -Fructus Psoralen and Flos Carthami in Baiban paste were identified by TLC. The contents of Psoralen and Isopsoralen in Baiban paste were determined by HPLC. RESULTS: The TLC spots of both Fructus Psoralen and Flos Carthami were clear with good resolution and free of interference of negative samples. The linear ranges of Psoralen and Isopsorale wre 13.44~67.20 ng and 12.00~60.00 ng, respectively. The average recoveries were 98.86%(RSD=1.09%, n=6) and 98.84%(RSD=1.29%, n=6), respectively. CONCLUSION: The established standard is applicable for the quality control of Baiban paste.
