title: [Studies on chemical constituents in herb of Lamium maculatum L. var Kansuense].
abstract: OBJECTIVE
  To study the chemical constituents from Lamium maculatum L. var Kansuense.
  
  
  METHODS
  The chemical constituents were isolated and repeatedly purified by silica gel column chromatography and the structures were elucidated by the NMR spectra and physico-chemical properties.
  
  
  RESULTS
  Ten compounds were obtained and they were identified as D-mannitol, beta-sitosterol, stigmasterol, rutin, 3'-methylquercetin-3-O-rutinoside, n-butyl-beta-D-fructopyranoside, daucosterol, acteoside, 20-hydroxyecdysone, allantoin.
  
  
  CONCLUSIONS
  All the compounds were obtained from L. maculatum L. var Kansuense for the first time.
