title: [Study on releasing rate of chrysophanol from Ruyi Jinhuang plaster].
abstract: OBJECTIVE
  To study the releasing rate of chrysophanol from Ruyi Jinhuang plaster.
  
  
  METHODS
  Based on the detecting methods of releasing rate and residual dosage applied in (Pharmacopoeia of P. R. C) (2000 edition), the contents of chrysophanol were detected by HPLC.
  
  
  RESULTS
  Chrysophanol in Ruyi Jinhuang plaster could well be released from plaster and to form medicinal concentration gradient.
  
  
  CONCLUSIONS
  Chrysophanol in Ruyi-Jinhuang plaster can possibly be absorbed by skin.
