title: [Studies on chemical constituents in herb of Lamium maculatum var. kansuense (II)].
abstract: OBJECTIVE
  To study the chemical constituents from Lamium maculatum var. kansuense.
  
  
  METHODS
  The chemical constituents were isolated and repeatedly purified on silica gel column and the structures were elucidated by the NMR spectra and physico-chemical properties.
  
  
  RESULTS
  Six compounds were obtained and identified as polypodine B (I), 5-OH-8-epiloganin (II), shlanzhiside methyl ester (III), liriodendrin (IV), quercitroside (V), uridine (VI).
  
  
  CONCLUSIONS
  Compound IV was found from genus Lamium for the first time and the rest of the compounds were found from Lamium maculatum var kansuense for the first time.
