Pharmacokinetics and brain distribution differences of baicalin in rat underlying the effect of Panax notoginsenosides after intravenous administration.

Baicalin (BA) is the most well-known flavonoid present in Radix Scutellariae. The aim of this study was to explore whether the pharmacokinetic behavior of BA in rat brain can be affected by Panax notoginsenosides (PNS), and to assess the possible mechanism for the observed effects. Specific HPLC and HPLC/MS/MS methods were developed and validated for the… CONTINUE READING
