ABSTRACT
OBJECTIVE:
To establish a determination method for trace elements of Plumbago zeylanica.METHODS:
Induct- ively coupled plasma emission spectrum (ICP-AES) was used to determine seven trace elements of P. zeylanica, i.e. Cu, Zn,Fe,Ca,Mg,Mn and Sr simultaneously. Se was determined by atomic fluorescence (AFS) method.RESULTS:
The RSD ranged from 0.78% to 3.01%(n=5),while the recovery was within 91.9%~105.8%. The result obtained was satisfactory. Se took a large proportion in P. zeylanica, followed by Cu,Zn,Fe,Ca,Mg,Mn,Sr.CONCLUSION:
The method is brief, rapid and accurate for the determination of P. zeylanica. The study provide reference for future pharmacological study of P. zeylanica.
