Validated LC–MS/MS assay for quantitative determination of deoxypodophyllotoxin in rat plasma and its application in pharmacokinetic study.

Highlights: [•] A LC–MS/MS method was first developed and validated for the determination of deoxypodophyllotoxin in rat plasma. [•] Good peak shape and sensitivity with acceptable matrix effect could be obtained. [•] It is the first pharmacokinetic study of the intravenous administration of DPT in rats. [•] The pharmacokinetic parameters were obtained through two-compartment intravenous models analysis. [ABSTRACT FROM AUTHOR]
