Analysis of Pharmacokinetic Behavior of Five Components in Qingkailing (Lyophilized) for Injection in Normal Rats and Cerebral Ischemia Rats by UPLC-MS/MS
To establish a UPLC-MS/MS analysis method for determination of baicalin
geniposide
chlorogenic acid
cholic acid and hyodeoxycholic acid in Qingkailing (lyophilized) for injection in rat plasma
and to investigate the pharmacokinetic behavior of this preparation in normal and cerebral ischemic rats.
Method:
2
Rats were randomly divided into normal group and cerebral ischemia model group. The rat model of cerebral ischemia was established by suture embolization. The rats were given by intraperitoneal injection
and normal saline was used as the solvent. Blood samples were taken at the corresponding time points. After treatment
UPLC-MS/MS was used to determine the blood concentration of five components. The main detection conditions were mobile phase of 0.1%formic acid aqueous solution-acetonitrile for gradient elution (0-0.25 min
90%A; 0.25-1 min
90%-75%A; 1-2 min
75%-50%A; 2-2.6 min
50%-45%A; 2.6-2.65 min
45%-90%A; 2.65-4.0 min
90%A)
the flow rate of 0.4 mL·min
-1
the column temperature at 40 ℃
electrospray ionization under negative ion mode. The pharmacokinetic parameters were fitted and the bioavailability was calculated
the differences of treatment process of five components from Qingkailing (lyophilized) for injection in normal and cerebral ischemic rats were analyzed.
Result:
2
Compared with the normal group
the area under the curve (AUC
0-
t
) of geniposide in rats from cerebral ischemia model group decreased significantly after intraperitoneal injection of Qingkailing (lyophilized) for injection (
P
<
0.05)
and the time to peak (
T
max
) of chlorogenic acid in rats from cerebral ischemia model group was significantly earlier than that in the normal group (
P
<
0.01). Pharmacokinetic parameters of baicalin
cholic acid and hyodeoxycholic acid had no significant difference between these 2 groups.
Conclusion:
2
Qingkailing (lyophilized) for injection has a certain difference in the treatment process between normal and cerebral ischemic rats
which has certain guiding significance for the clinical treatment of cerebral ischemic diseases with this preparation.
