Study of extraction technology of paeonol in Cortex Moutan

  • Datong Seventh People Hospital,Datong 037005,China

  • Received Date: 2006-02-28
  • Objective:To study the extraction technology of paeonol from Cortex Moutan,and improve the extraction method of steam distillation with ultrasonic assistance. Methods: The paeonol was determined by HPLC method in Chinese Pharmacopeia 2005. The distilled water amount,alcohol addition amount and uhransonic time,meanwhile were conpared,the extraction amounts of paeonol in distillate were calculated. Results: The final affirmed method of paeonol extraction was ten times distilled water and transonic twenty minutes,then distill until the distillate was not turbid. Conclusion: The final method was pretreated by ultrasonic which could increase the extraction efficiency greatly,and has the advantages of simple,economic and low toxicity,also can be used in the large-scale prep- aration of paeonol.
