ABSTRACT
<p><b>OBJECTIVE</b>To study the interactions between Ligusticum chuanxiong Hort extract and cardiac muscle membrane receptors.</p><p><b>METHOD</b>The cell membrane of rabbit cardiac muscle was fixed on silicon to make cell membrane stationary phase (CMSP), and then the interactions were studied by comparing the retention characteristics of the extracts from different solvents with those of the antagonists or activators corresponding to known receptors in cardiac muscle membrane, and by competition effect on the retention characteristics of extracts when adding the antagonists or activators into the mobile phase.</p><p><b>RESULT</b>Water extract and ethanol extract both had retentions on CMSP; the retention characteristics of water extract could be affected when water extract was in competition with the antagonists for alpha receptor, and could not be affected when with the activator beta1 receptor.</p><p><b>CONCLUSION</b>It is possible that some components in water extract may combine with alpha receptor and no component with beta1 receptor, and that some components in ethanol extract may combine with cardiac muscle cell membrane. The process between active components and receptors in vivo can be imitated through the interactions between drugs and CMSP. The method provides references for the resolution of two applications to screen the active components from Chinese medicine, and to figure out the type of receptors involved.</p>
