Determination of plasma protein binding rate of multicomponent in Dengzhanxixin injection
摘要
Abstract
Aim To establish a detection method for determination of concentration of six major compounds in Dengzhanxixin injection in rat plasma and to study the plasma protein binding rate. Methods The equilibrium dialysis was carried out to determine the plasma protein binding rate of multicomponent in Dengzhanxixin injection , and the drug concentration was detected by HPLC method. The biological samples were all handled with acetic ether-extracting. Results The average plasma protein binding rates of six compounds at low,middle and high concentrations were as follows , respectively : caffeotannic acid was ( 76. 94 ± 3. 72 )% , caffeic acid was ( 91. 57 ± 0. 96 )% ,1.5-DCQA was ( 83. 32 ±3. 73 )% , scutellarin was ( 91. 66 ± 0. 71 )% .3 ,5DCQA was ( 95. 73 ±0. 67 )% ,3,4-DCQA was ( 94. 21 ±0. 65 )%. Conclusions The HPLC method is used for the first time to determine the concentration of multicomponent in Dengzhanxixin injection. The method is simple, reliable and stable. The six major compounds in Dengzhanxixin injection have high capacity in binding to plasma protein in rat in vitro.关键词
