Abstract

The invention discloses a preparation method and medicinal application of CHB which is an effective component of bupleurum Chinese and particularly relates to an application of CHB in preparation of a product for treating depression. The CHB which is the effective component of the bupleurum Chinese has a good effect on treating depression caused by various factors, has a certain protection effect on a U251 cell damaged by corticosterone and has the effects of shortening the tail-suspending immobility time and the swimming immobility time of a mouse and improving the decrease of the body temperature of the mouse due to reserpine. Each dose group is significantly and statistically different from the model group, is dose-dependent and has a good antidepressant function.

Description

technical field [0001] The invention relates to the field of traditional Chinese medicine, in particular to the application of the active component CHB extracted from Bupleurum bupleuri and the antidepressant biological activity of the component. Background technique [0002] As the pace of life in modern cities continues to accelerate, people are under increasing pressure, and the incidence of depression is also increasing year by year. Depression, characterized by persistent low mood and cognitive impairment, is a chronic and recurrent brain disease affecting 20% ​​of the world's population.
