title: [Spectrum-active relation research on Typha angustifolia before and after carbonized].
abstract: OBJECTIVE
  To study the components of Typha angustifolia change before and after carbonized and the correlation with its effective.
  
  
  METHODS
  The chemical constitutions between the pollen and its carbonized product were compared by UPLC-MASS and their thrombin activity was tested.
  
  
  RESULTS
  The change of components was significant especially the flavonoids. The content of flavonoid glycoside was reduced obviously and the thrombin activity showed the main difference was quercetin and isorhamnetin.
  
  
  CONCLUSIONS
  The flavonoids in pollen typha may be the main factors in their thrombin activity.
