Figure 2.
Plasma concentrations of total flavonols (circles filled in yellow) and terpene lactones (circles filled in pink) over time after a 15 min i.v. infusion dose of ShuXueNing injection (upper panel) or a p.o. dose of GBE50 (lower panel) in rats. The test dose levels of ShuXueNing injection included 1 (green curves), 2 (blue curves) and 4 mL·kg−1 (red curves), and those of GBE50 were 10 (green curves), 30 (blue curves) and 90 mg·kg−1 (red curves). The inserts are the associated semilogarithmic plots of the plasma concentrations of ginkgo compounds over time after administration of ShuXueNing injection.
