Abstract:
OBJECTIVETo study zedoary turmeric oil (ZTO) and the pharmacokinetics of its homemade compound antiviral preparation in New Zealand rabbits.
METHODRP-HPLC was used to determinate the content of germacrone in rabbit plasma after oral administration.
RESULTAfter oral administration of ZTO and its homemade compound antiviral preparation, the plasma concentration-time curve of germacrone is in conformity to two-compartment open model. The pharmacokinetic parameters of ZTO: t1/2alpha, t1/2beta, Vd, CL, AUC and Ka were (1.52 +/- 0.59), (1.97 +/- 0.27) h, (47.59 +/- 2.29) L x kg(-1), (176.77 +/- 7.65) L x h(-1) x kg(-1), (5.70 +/- 0.70) mg x h x L(-1) and (0.97 +/- 0.11) h(-1), respectively, while those of compound preparation were (0.41 +/- 0.03), (1.47 +/- 0.35) h, (75.21 +/- 5.21) L x kg(-1), (287.79 +/- 6.39) L x h(-1) x kg(-1), (3.91 +/- 0.53) mg x h x L(-1) and (5.14 +/- 1.26) h(-1), respectively. There was no significant difference between the above two groups of pharmacokinetic parameters, expect that Ka of compound preparation was significantly higher than that of ZTO (P < 0.05).
CONCLUSIONHypericum perforatum in compound preparation doesn't impact the distribution and elimination of active ingredients of ZTO in New Zealand rabbits, but it improves the absorption speed, and shortens the time of drug absorption, which contributes to rapid efficacy of ZTO in rabbits.
