Objective: To establish an HPLC method for simultaneous determination of three components in Ershen pills and compare the content changes of psoralen
isopsoralen and dehydrodiisoeugenol in this prescription before and after processing
and to investigate the influence of processing on chemical compositions. Method: Psoralea was stir-fried with salt and Nutmeg was roasted with wheat bran.HPLC was applied to determine the content changes of psoralen
isopsoralen and dehydrodiisoeugenol in this prescription before and after processing. Result: The average recoveries of psoralen
isopsoralen and dehydrodiisoeugenol were 101.76%
96.15%
99.61%
with RSD being 2.02%
1.55%
1.96%.The psoralen
isopsoralen and dehydrodiisoeugenol samples showed a good linear relationship in the ranges of 0.164-2.05
0.115-1.44
0.086 4-1.08 μg
respectively
in the chosen HPLC conditions.After preparation
the three compositions were reduced. Conclusion: The method is simple
accurate and reproducible. The contents of psoralen
isopsoralen and dehydrodiisoeugenol in Ershen pills can be changed after processing.
