%X Static adsorption dynamics equations of Rutin and Baicalin were established on the basis of same experiment conditions to reveal and prove the effect of compound structure on static adsorption in macroporous resin. At ambient temperature, the macroporous resin AB-8 was selected to adsorb Rutin and Baicalin in the same molarity conditions respectively. The adsorption data in the different time were determined by HPLC, and were counted according to the formulas. Then, static adsorption kinetic curves were drawn. And the static adsorption dynamics equations of both Rutin and Baicalin were established by regression method. The static adsorption dynamics equation for Rutin is Y = 4.715X2+0.013X1X2, and for Baicalin is Y = 4.921X10.006X2; where Y is static adsorption (mg/g), X1 is the time of adsorbing (h), and X2 is concentration of the sample (mg/ml). The type of static adsorption dynamics equations and the static adsorptive rules of Rution and Baicalin are different. There are obvious differences. Results indicated that compounds structure of flavonoids have significant influence to macroporous resin static adsorption. It is very important to study the adsorptive internal relations of compound structures and macroporous resin. There are guiding roles and theoretical values to optimize the technology of extraction and to improve the extractive efficiency and selectivity.
