Abstract: Objective：To determine the content of costunolide and dehydrocostus lactone in different batches of aucklandiae radix stir fried with bran and under different bran fry conditions，and to establish a reasonable，feasible and relatively high-quality processing technology，so as to provide reference for establishing the processing standard of aucklandiae radix stir fried with bran， and the production of aucklandiae radix stir fried with bran.Methods： Thin layer chromatography(TLC) was used to identify aucklandiae radix stir fried with bran.The content of two main components， costunolide and dehydrocostus lacton were determined by high performance liquid chromatography(HPLC). Results： Different process method directly affected the content of costunolide and dehydrocostus lacton. The dosing ratio of aucklandiae radix to bran was feasible in the range of 10∶1-6.6∶1， and when the dosing ratio was 6.6∶1， the content of costunolide and dehydrocostus lacton was higher. Stir-frying time in 6-8 min was appropriate， the content of costunolide was higher when fried for 6 min， and the content of dehydrocostus lactone was higher when fried for 8 min. Conclusion： The established processing method is simple， feasible， accurate and reproducible， and can be used to control the quality of aucklandiae radix stir fried with bran.
