ABSTRACT
Objective:
To analyze and identify the brain and blood absorption components of rats after intragastric administration of Buyang Huanwu Tang(BYHWT).Method:
The brain tissue,plasma of normal rats and the cerebral ischemia-reperfusion rats were analyzed by UPLC-Q-TOF-MS/MS.The prototype components in BYHWT were identified according to retention time,accurate relative molecular weight,primary and secondary mass spectrometry data.Result:
After the administration of BYHWT,five compounds were found to enter the normal brain tissue through the blood-brain barrier and identified as calycosin-7-glucoside,albiflorin,formononetin-7-O-β-D-glucoside-6″-O-acetyl,safflower yellow A and astragaloside A;two compounds penetrated the blood-brain barrier and entered modeling brain tissue,and they were identified as calycosin-7-glucoside and formononetin-7-O-β-D-glucoside-6″-O-acetyl;seven compounds entered normal plasma and were identified as calycosin-7-glucoside,albiflorin,hydroxysafflor yellow A,et al;three compounds entered model plasma and identified as calycosin-7-O-β-D-glucoside-6″-O-acetyl,6″-O-acetyl-(6αR,11αR)-9,10-dimetho-xypterocarpan-3-O-β-D-glucoside and formononetin-7-O-β-D-glucoside-6″-O-acetyl.Conclusion:
BYHWT has different pharmacological material basis in normal and cerebral ischemia-reperfusion rats.
