Abstract

BACKGROUND:

Callicarpae Caulis et Folium (CCF) is a traditional Chinese medicine usually used for hemostasis in clinics. In this study, a novel LC-MS/MS method was developed and validated for the simultaneous quantification of three phenylethanoid glycosides in rat plasma (verbascoside, forsythoside B and poliumoside), which are the major bioactive compounds of CCF; MS was operated in negative mode.

RESULTS:

This method was linear between 5.2 and 1010 ng/ml for poliumoside, 7.0 and 420 ng/ml for forsythoside B and 2.60 and 260.0 ng/ml for verbascoside. The MS/MS ion transitions monitored were m/z 769.4→160.5, m/z 755.3→593.3, m/z 623.1→160.5 and m/z 179.0→133.6 for poliumoside, forsythoside B, verbascoside and caffeic acid (IS), respectively. Linearity, accuracy, precision and extraction recovery of three analytes were all satisfactory.

CONCLUSION:

The method developed was sensitive, specific and rapid. It has been successfully applied in a PK study of three phenylethanoid glycosides after a single oral administration of CCF extract to rats.
