Objective: Study the dissolution of ferulic acid in Danggui Buxue Pill
in order to control the quality of pill. Method: Paddle method was chosen and the content of ferulic acid of the pill in different sample time was measured by HPLC. At last time
the dissolution percentage was accounted
to fit the Weibull model and get the dissolution parameters of T50 and Td by SAS software. Result: The dissolution percentage of ferulic acid in Danggui Buxue Pill was 95% in four hour of sample time
and the best dissolution model was Weibull model. The T50and Td of ferulic acid were 47min and 69min. Conclusion: The established dissolution method was accuracy
sensitive and simple. It can be used for quality control of Danggui Buxue Pill.
