title: Pharmacokinetic study of p-coumaric acid in mouse after oral administration of extract of Ananas comosus L. leaves.
abstract: Quantification of p-coumaric acid in mouse plasma following oral administration of Ananas comosus L. leaves was achieved by reversed-phase high-performance liquid chromatography using a mobile phase of water-acetonitrile (82:18, v/v) and UV detection at 310 nm. The method was linear (determination coefficient, r2 = 0.9997) within the tested range (0.04-1.28 microg/mL). Intra- and inter-day precision coefficients of variation and accuracy bias were acceptable (maximal CV value was 4.06% for intra-day and 4.19% for inter-day) over the entire range. The recoveries were 90.63, 97.98 and 100.01% for concentrations of 0.04, 0.32 and 1.28 microg/mL, respectively. This is a very rapid, sensitive and economical way to determine p-coumaric acid concentration in mouse plasma after oral administration of A. comosus leaves. The concentration-time curve was fitted to the one-compartment model. This is the first time that p-coumaric acid extracted from A. comosus leaves was detected by HPLC-UV method and its pharmacokinetic characteristic was comprehensively studied.
