Spectrum-active Relation Research on Typha angustifolia before and after Carbonized

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.Conclusion: The flavonoids in pollen typha may be the main factors in their thrombin activity.
