UPLC-Q-TOF-MS/MS Analysis of Brain and Blood Absorption Components of Buyang Huanwu Tang After Intragastric Administration
To analyze and identify the brain and blood absorption components of rats after intragastric administration of Buyang Huanwu Tang(BYHWT).
Method:
2
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:
2
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-
