ABSTRACT

Objective: To analyze the quality of Angelicae Dahuricae Radix (ADR) from national drug evaluation sampling, continuously improve and revise the standard determination method, and ensure the safety of public drug use, six index components of ADR medicinal material and decoction pieces were determined by combining HPLC fingerprint chromatography and quantitative analysis of multi-components by single marker (QAMS). Methods: The determination and exploratory study were carried out according to the National Standard. The establishment of steamed Angelicae dahurica HPLC fingerprint, method for multiple assessment of six index components to conduct a methodological survey determination of multi-index component content of 20 batches of Angelicae dahurica tablets, the final determination of the quality of Angelicae dahurica. Result:s A total of 239 batches of ADR were received from 189 enterprises, in which 225 batches were qualified and 14 batches were unqualified. The qualified rate was 94%. A method that determined content of six kinds of coumarin in ADR decoction pieces using imperatorin as control was established, which could solve the problem of difficulty in obtaining control and consuming long determination time. It would better indicate the drug quality. Conclusion The method we had established could be used in qualitative and quantitative analysis of oxypeucedanin hydrate, byakangelicin, oxypeucedanin, berapten, imperatorin and isoimperatorin in ADR decoction pieces. Through this random inspection, it is found that there were still some quality problems in ADR decoction pieces. The quality supervision of traditional Chinese medicine should be strengthened further.
