The results showed that there were clear spots, good degree of separation, and no negative interference in the TLC identification. The calibration curve of costunolide and dehydrocostunolide were linear at the range of 0.103 4-1.033 5μg (r=0.999 9) and 0.110 1-1.100 5μg (r=0.999 7). The average recoveries were 95.1% (RSD = 2.62%, n = 6) and 98.6% (RSD = 2.84%, n = 6), respectively. It was concluded that the method was convenient and accurate with strong specificity in the quality and quantity control of PA pill, which can be used in the quality control of PA pill.
