Liquid chromatography–mass spectrometry analysis of macranthoidin B, macranthoidin A, dipsacoside B, and macranthoside B in rat plasma for the pharmacokinetic investigation   

METHODS AND RESULTS:

A liquid chromatography-electrospray ionization–mass spectrometry method has been developed and validated for identification and quantification of four major bioactive saponins in rat plasma after oral administration of extraction of saponins from Flos Lonicerae, i.e., macranthoidin B, Macranthoidin A, dipsacoside B, and macranthoside B. Plasma samples were extracted with solid-phase extraction, separated on a Shim-pack CLC-ODS column and detected by MS in negative selective ion monitoring mode. Calibration curves offered linear ranges of two orders of magnitude with r2 > 0.999. The method showed the low limit quantification of 7.72, 6.06, 7.16, and 1.43 ng/mL for macranthoidin B, Macranthoidin A, dipsacoside B, and macranthoside B, respectively. The inter- and intra-CV precision (R.S.D.) were all within 10% and accuracy (% bias) ranged from −10 to 10%. The overall recovery was more than 70%. 

CONCLUSIONS:

This developed method was subsequently successfully applied to pharmacokinetic profiles of the four saponins in rats. After oral administration of extraction of saponins in rats, the concentration–time course was found to be the double peaks of curve.
