title: [High performance liquid chromatographic method for the determination of ipriflavone in serum and its pharmacokinetic study in healthy volunteers].
abstract: A sensitive and rapid high performance liquid chromatographic method has been developed for the determination of ipriflavone in human serum. The average recovery of ipriflavone was 85% with relative standard deviation of 3.8%-5.4%. The calibration curve was linear in the range from 8 ng.ml-1 to 400 ng.ml-1 with gamma = 0.9981. The detection limit of the method was 3 ng.ml-1 (S/N > or = 3). The serum drug concentration-time curve exhibited a 2-compartment model and the mean T1/2 beta was 12.00 +/- 1.89 h (for ipriflavone made in Japan) and 9.05 +/- 0.80 h (for ipriflavone made in China). The AUC0-->infinity of the two kinds of ipriflavone were 804.99 ng.h.ml-1 and 807.40 ng.h.ml-1, respectively. The relative bioavailability of ipriflavone made in China vs that made in Japan was 1.003.
