Simultaneous quantification of free curcuminoids and their metabolites in equine plasma by LC-ESI-MS/MS.

Abstract: The human health benefits attributed to turmeric/curcumin spice has resulted in its wide utilization as a dietary supplement for companion pets and other animals including horses. While the quantification of free curcuminoids (curcumin, demethoxycurcumin, bisdemethoxycurcumin) and their phase-2 metabolites (curcumin-O-sulfate, curcumin-O-glucuronide) have been extensively investigated in human and rodent biological samples (primarily plasma and serum), there is lack of similar data for horses. Herein, we report a validated LC-ESI-MS/MS method for the simultaneous quantification of the aforementioned free curcuminoids and their metabolites in equine plasma. The linearity of the aforementioned curcuminoids and curcumin-O-sulfate was in the range of 0.5-1000 ng/mL and 1-1000 ng/mL for curcumin-O-glucuronide with 85-115% accuracy and <15% precision in equine plasma. The method was validated based on US FDA criteria and applied to characterize the pharmacokinetics of curcumin-O-sulfate in equine plasma.

This research paper presents a method for measuring the levels of curcuminoids and their metabolic products in horse blood. It examines the use of turmeric/curcumin as a dietary supplement for animals like horses using Liquid Chromatography with Mass Spectrometry/Mass Spectrometry (LC-ESI-MS/MS), a common tool used in drug discovery.

Background

  • Turmeric, and its primary active compound, curcumin, have been attributed with significant health benefits in humans, leading to its widespread use in dietary supplements. These supplements aren’t limited to human consumption, and are also used in companion pets like cats, dogs, and other animals, including horses.
  • While the different types of curcuminoids (curcumin, demethoxycurcumin, and bisdemethoxycurcumin) and their metabolic byproducts (curcumin-O-sulfate and curcumin-O-glucuronide) have been widely studied in human and rodent samples, there’s a noticeable lack of similar data for horses.

Methodology

  • The study uses LC-ESI-MS/MS, a common bioanalytical method, for the simultaneous measurement of the target curcuminoids and their metabolites in equine plasma.
  • The established method was validated against the U.S. Food and Drug Administration (FDA) criteria.

Results

  • The range in which the curcuminoids and curcumin-O-sulfate could be effectively measured was between 0.5-1000 ng/mL, and 1-1000 ng/mL for curcumin-O-glucuronide. This was with a stated accuracy of 85-115% and a precision of under 15% in the equine plasma.
  • The validated method was then applied to determine the behaviour of curcumin-O-sulfate in horse blood over time, or its pharmacokinetics.

Through this research, a validated process now exists to quantify and understand the impact of dietary turmeric/curcumin supplement consumption on equine health. This can be used to further study dosage, efficacy and any potential side effects.
