蛭蛇通络胶囊的入血、入脑成分研究

Analysis of constituents absorbed into blood and brain from Zhishe Tongluo Capsules

目的分析蛭蛇通络胶囊入血、入脑成分。方法16只大鼠随机分为4组,灌胃给药(3.1 g/kg),建立脑缺血再灌注损伤(MACO)模型,取血和脑组织,UHPLC-Q Exactive Focus MS/MS法鉴定原型成分。结果共鉴定出70种成分,血浆中有20种,主要为黄酮类、丹参醌类、川芎苯酞类,7种能透过血脑屏障进入脑组织。与正常给药组比较,MACO给药组入血成分增加间羟基苯甲酸、毛蕊异黄酮苷、莪术烯醇、洋川芎内酯B、二氢丹参酮Ⅰ、隐丹参酮;左脑组织(梗死侧)入脑成分减少葛根素、榄香素、新蛇床内酯,增加丹酚酸A、洋川芎内酯I、二氢丹参酮Ⅰ。结论蛭蛇通络胶囊入血、入脑成分及脑缺血再灌注损伤大鼠体内增强吸收的苯酞类、醌类、酚类成分可能是治疗脑梗塞的活性物质。

AIM To analyze the constituents absorbed into blood and brain from Zhishe Tongluo Capsules.METHODS Sixteen rats were randomly assigned into four groups and given intragastric administration(3.1 g/kg),after which the cerebral ischemia-reperfusion injury(MACO)model was established,the blood and brain tissues were collected,and UHPLC-Q Exactive Focus MS/MS was adopted in the identification of prototype constituents.RESULTS Total 70 constituents were identified,20 of which were found in the blood,mainly including flavonoids,tanshinones and Ligusticum chuanxiong phthalides,and 7 of them could enter the brain through blood-brain barrier.Compared with the normal administration group,the MACO administration group demonstrated added constituents absorbed into blood containing 3-hydroxybenzoic acid,calycosin-7-glucoside,curcumenol,senkyunolide B,dihydrotanshinone I and cryptotanshinone;removed constituents absorbed into brain containing puerarin,elemicin,sedanolide,and added those containing salvianolic acid A,senkyunolide I,dihydrotanshinone I in the left brain tissues(infarcted side).CONCLUSION The constituents absorbed into blood and brain from Zhishe Tongluo Capsules,along with the enhanced absorptions of phthalides,quinones and phenols in MACO rats in vivo may be the active substances for treating cerebral infarction.
