ABSTRACT

AIM: To research the processed products of Rhizoma Atractylodis Macrocephalae at the level of sesquiterpene lactones from it. METHODS: Sesquiterpene lactones were separated by the silica gel column and layer preparation, and the active substances were determined by HPLC. RESULTS: Atractylone、atractylolide Ⅰ, atractylolide Ⅲ, and biepiasterolid were separated from Rhizoma Atractylodis Macrocephalae. Atractylone was (0.535 8)%, atractylolide Ⅰ was (0.044 0)% and actractylolide Ⅲ was (0.081 4)% in Atractylodis stir-fried with wheat bran determined by HPLC. CONCLUSION: The method has good accuracy and repeatability and it can be used for the quality control of Rhizoma Atractylodis Macrocephalae.
