[Study on absorbed components of Aconitum kusnezoffii under Yunnan Baiyao compatibility in effect of activating blood circulation and removing blood stasis].

Rat model of blood stasis syndrome was prepared by subcutaneous injecting of epinephrine hydrochlorid,then the model rats were administrated by Yunnan Baiyao for 15 days. Blood rheology,coagulation function and histopathology were chosen as indicators to evaluate the successful replication of blood stasis syndrome model and the treatment effect of Yunnan Baiyao. UPLC-Q-TOF-MS was used to rapidly analyze the serum samples of blood stasis syndrome rat after 15 days Yunnan Baiyao treatment,Progenesis QI software was employed to identify the alkaloids components. The results showed that Yunnan Baiyao reduced the plasma viscosity and whole blood viscosity of rats with blood stasis syndrome,prolonged thrombin and prothrombin time,reduced fibrinogen content,and effectively improved pathological state such as inflammatory cell infiltration,blood stasis,congestion and edema of various organs in rats with blood stasis syndrome. Seven alkaloids components from Aconitum kusnezoffii,including karacolidine,senbusine B,isotalatizidine,karakoline,denudatine,talatisamine and chasmanine were found in the rat serum after Yunnan Baiyao treatment. Based on the effectiveness of Yunnan Baiyao in the treatment of blood stasis syndrome induced by epinephrine hydrochloride in rats,alkaloids components from the root of A. kusnezoffii absorbed into blood after Yunnan Baiyao treatment were clarified rapidly and accurately with the help of UPLC-Q-TOF-MS. Karacolidine,senbusine B,isotalatizidine,karakoline,denudatine,talatisamine and chasmanine are the pharmacodynamic material basis of the root of A. kusnezoffii for activating blood circulation and removing blood stasis.
