title: [Analysis of inorganic elements of several species from Moghania genus and M. philippinensis from different habitats].
abstract: OBJECTIVE
  To compare the contents of inorganic elements in root, stem and leaf of several species from Moghania genus and root of M. philippinensis from different habitats.
  
  
  METHODS
  Inductively Coupled Plasma Optical Emission Spectrum (ICP-OES) was used to determine twenty five inorganic elements simultaneously. The correlation analysis, principal component analysis and cluster analysis were applied for the study of inorganic elements.
  
  
  RESULTS
  The content of inorganic elements from different species was difference. As for M. philippinensis from different habitats, the content sequence was Guangxi > Jiangxi > Guangdong > Sichuan. There was significant correlation between different inorganic elements. The principal component analysis results showed that V, Co, K, Fe, Cr, P, Mo, Si, Na, Ca and Mg might be the characteristic elements of these species from Moghania genus. The results of cluster analysis showed that M. philippinensis and M. strobilifera could be separated and M. philippinensis from Guangxi, Jiangxi, Guangdong and Sichuan could be separated.
  
  
  CONCLUSIONS
  This experiment provided theoretical basis for distinguish and quality assessment of species from Moghania genus and M. philippinensis from different habitats.
