Abstract
Coptidis Rhizoma (CR) has been used widely in traditional medicine to treat common diseases. This study aimed to develop a high-sensitivity liquid chromatography-tandem mass (LC-MS) spectrometry method for the evaluation of the pharmacokinetics of a new natural product that contain CR extract with the main bioactive compound, berberine, at trace concentrations. Human plasma samples were pretreated with methanol by a protein precipitation method. Berberine was analyzed on a Kinetex C18 column (2.1 mm × 50 mm, 100 Å, 1.7 µm) using a mobile phase of 10 mM ammonium formate/0.1% formic acid in water (A) and acetonitrile (B) (50:50, v/v) with a flow rate of 0.25 mL/min. The analyte was detected by using electrospray ionization in positive mode with multiple reaction monitoring (MRM). The method was sensitive, with a lower limit of quantification of 1 pg/mL, which has not been previously obtained. The method was validated (over the range of 1–50 pg/mL) and applied successfully for the pharmacokinetic study of human plasma samples.
