Objective:
To investigate the pharmacokinetics and bioavailability of ginsenoside Rg1 in rats.
Methods:
Ginsenoside Rg1 was oral administered or intravenous administered to each rat. The plasma concentration of ginsenoside Rg1 was estimated by RP-HPLC. 3P97 software was used to calculate pharmacokinetic parameters.
Results:
Main parameters of ginsenoside Rg1 after oral or intravenous administered were: AUC(0 --> t), 322.70 +/- 20.78, 99.76 +/- 8.91 microg x h/mL, CL 0.08 +/- 0.02, 3.01 +/- 0.69 L/(kg x h), V 0.23 +/- 0.01, 22.75 +/- 2.09 L/kg, t1/2alpha 0.48 +/- 0.18, 0.87 +/- 0.21 h, t1/2beta 19.57 +/- 2.81, 18.68 +/- 2.74 h, MRT6.91 +/- 0.99, 8.15 +/- 1.05 h(-1), respectively. The relative oral bioavailability of ginsenoside Rg1 was 2.5%.
Conclusion:
The oral bioavailability of ginsenoside Rg1 is very low.
