[Study on the quantitative change of anthraquinonoids of Rhei in the preparation of dachengqi].
OBJECTIVE
To study the scientific evidence of the traditional preparation of Dachengqi: "Boiling Aurantii Immaturus and Magnoliae Officinalis first, and then adding Rhei to decoct together. Discarding the dregs, adding Natrii Sulfas into the decoction and drinking the upper solution when the Natrii Sulfas has dissolved completely".


METHODS
The concentrations of free and combined anthraquinonoids(emodin, rhein, chrysophanol, physcion) in different decoctions were determined with HPLC method respectively.


RESULTS
When Natrii Sulfas, Aurantii Immaturus and Magnolias Officinalis are decocted with Rhei in different schemes, the concentrations of anthraquinonoids were changed regularly.


CONCLUSIONS
The scientific evidence of traditional preparation method greatly increased the concentrations of the active components in Dachengqi.
