Fatty
acid esters of 3-monochloropropane 1,2-diol (3-MCPD) are
a group of processing-induced toxicants. To better clarify their possible
toxicological effects and mechanisms, it is important to investigate
their absorption, distribution, metabolism, and excretion. In this
study, the kinetic parameters of 3-MCPD dipalmitate in Sprague Dawley
(SD) rat plasma were determined using ultraperformance liquid
chromatography–triple quadrupole mass spectrometry. 3-MCPD
dipalmitate was absorbed in rats with a C
max of 135.00 ng/mL, a T
1/2 of 3.87 h, a T
max of 2.5 h, an MRT of 5.08 h, a CL of 3.50
L/h/g, a V
d of 21.34 L/g, and an AUC0–∞ of 458.47 h·ng/mL. A total of 17 metabolites
were identified, and 16 of them were reported for the first time.
Furthermore, these metabolites were examined for their presences in
the liver, kidney, testis, brain, spleen, thymus, intestine, plasma,
feces, and urine samples 2, 6, 12, 24, and 48 h after oral administration
of 3-MCPD dipalmitate using Metabolynx software.
