Metabolism of curcumin--studies with [3H]curcumin

Toxicology. 1981-1982;22(4):337-44. doi: 10.1016/0300-483x(81)90027-5.


Radioactivity was detectable in blood, liver and kidney following dosage with 400, 80 or 10 mg of [3H]curcumin. The major route of elimination of the label was the feces; the urinary excretion of the label was very low regardless of the dose. At the lower doses of 80 mg and 10 mg of [3H]-curcumin, most of the label was excreted within 72 h, while with 400 mg, considerable amounts of the label was present in the tissues 12 days after dosage. The percentage of curcumin absorbed (60-66% of the given dose) remained constant regardless of the dose administered.
