Examining pharmacokinetics and excretion of α-cyperone in rats revealed low bioavailability, suggesting extensive metabolism.
α-Cyperone (C15H22O), a critical bioactive sesquiterpene, serves as a representative chemical compound of Cyperi Rhizoma—a classical functional food. To investigate the pharmacokinetic characteristics of α-cyperone, a quantified method was developed in plasma, bile, urine, and feces by ultra-high-performance liquid chromatography tandem triple quadrupole mass spectrometry (UHPLC-QQQ-MS/MS). After being validated, the developed method was applied in a plasma pharmacokinetic study as well as biliary, urinary, and fecal excretion kinetics studies. It revealed poor absolute bioavailability (F = 1.36%) and rare excretion (total cumulative excretion = 0.022%) of α-cyperone, which suggested extensive first-pass metabolism. This study provided crucial insight into explaining the in vivo process and promoting the further development of α-cyperone.
