Abstract:
OBJECTIVEThe objective of this paper is to investigate the pharmacokinetics of Chlorogenic acid (CA)and CA-Baicalin compound after intravenous injection (iv) in rabbits.
METHODTen rabbits were randomly divided into two groups. One group were administered CA (6 mg x kg(-1)) by iv, while the other were treated with CA (6 mg x kg(-1))-baicalin (90 mg x kg(-1)) compound by iv. administration. The concentration of CA in plasma was determined by HPLC. The key parameters of pharmacokinetics were calculated and analyzed by kinetic software.
RESULTBoth Concentration-time courses of CA alone and CA-Baicalin compound were consistent with a two-compartment model after administration. The key pharmacokinetic parameters of CA alone were significantly different from that of CA-Baicalin compound (P < 0.05). Compared with the group treated with CA alone, the group treated with CA-Baicalin compound had dramatic increased in AUC(0-infinity), MRT and T1/2alpha.
CONCLUSIONThere are significant difference between the pharmacokinetics of CA and CA-Baicalin compound in rabbits. Baicalin has impact on the pharmacokinetics of CA in rabbits.
