Quality Control of Wuzhuyu Decoction: from the Perspective of Smooth Muscle Actions
基于吴茱萸汤相关功效从平滑肌角度探讨其质量控制的可行性

To observe the action of Wuzhuyu decoction (evodiae complex) on smooth muscles, and discuss the possibility of the action as an assay of the complex quality control, a contraction test was made to blood vessels, stomach, small intestines and womb in vitro. Experimental results showed that the evodiae complex could regulate blood vessels in bi-phase, while reducing the tension of stomach and inhibiting the contraction of small intestines and womb smooth muscles. The fructus evodiae, a major ingredient in the complex, has the similar action with evodiae complex. The rest of the ingredients, including ginseng, jujube and ginger, appeared with a negative action on smooth muscles. It is suggested that the method be used for the comprehensive quality control of the decoction.
