【摘要】 [Objective]To determine the contents of inorganic elements in the stems of wild Plumbago zeylanica Linn. in different harvest periods( from January to December),and to discuss the effects of harvest period on the content of inorganic elements. [Methods]Microwave digestion and Inductively Coupled Plasma Optical Emission Spectrometer( ICP-OES) were both used to determine the inorganic elements in the stems of wild P. zeylanica. The detection results were researched by correlation analysis,principal component analysis and cluster analysis. [Results]The contents of inorganic elements in the stems of P. zeylanica varied in different harvest periods. Al,Ca,Fe,Sn,Ti,As,V, Zn,Mn,Mg and Ni were the eigenelements of P. zeylanica stems. Cluster analysis showed that the 12 samples of P. zeylanica stems could be divided into two categories: September was the first major category,and the others were the second category. [Conclusions]The detection results offered useful data for the synergic relationship among elements,and provided theoretical basis for the better utilization and development of P. zeylanica resources.
