The aim of the current study was to evaluate Morinda citrifolia (noni) seed extract, a food ingredient,
for potential toxicity and antioxidant activity. Nitrates, nitrites, phytic acid, oxalic acid, as well as aflatoxins
B1, B2, G1 and G2 were not detected in the extract. The extract was also non-cytoxic (LC50 > 1 mg/mL) in the
24 and 40 h brine shrimp toxicity test. There were no symptoms of toxicity in a subacute (28 day) oral toxicity
test in Sprague-Dawley rats. Noni seed extract did not display any genotoxic potential in a primary DNA
damage test in E. coli PQ37. The extract did exhibit significant antioxidant activity in the Oxygen Radical
Absorbance Capacity (ORAC) and Ferric Reducing Antioxidant Power (FRAP) tests.
Key words: Antioxidant, Morinda citrifolia, natural toxicants, noni, seed, toxicity tests,
