Objective :To study the metabolism of Gegen Qinlian dispensing granule in rat. Method : The urine samples containing metabolites of Gegen Qinlian dispensing granule were analyzed by HPLC-DAD-MS. Chromatographic systemwas composed of lichrospher C18 column (4.6 mm×250 mm
5 μm)
0.1% formic acid (A)-acetonitrile ∶methanol(6 ∶4)(B) as the mobile phase
detection at 272 nm; ESI source
positive and neglative mode. Result: Eleven components were identified as puerarin -glucoside
scutellarein-6-O-glucoside
puerarin
3' -methoxypuerarin
7-xylosidepuerarin
daidzein-4'-O-sulfate
Baicalein-6
7-O-diglucuronide
isoliquiritigenin
liquiritigenin
wogonin
oroxylin A. Conclusion: Metabolites of Gegen Qinlian dispensing granule in rat were conjugated to glycuronic acid and sulphuric acid or excreted as aglycone
some components such as puerarin were mainly excreted unchanged in the urine.
