The proralen and isoproralen in Qubai tablets were quantitatively determined by doublewavelength TLC-scanning. The average recoveryof proralen was found to be 98.96% and the relative standard deviation 2.86%(n=5);and the average recovery of isoproralen was 98.38%
with a relative standard deviation of 2.79%(n=5).The method was simple and rapid
