An anthraquinone with potent quinone reductase-inducing activity and other constituents of the fruits of Morinda citrifolia (noni).
The Journal of Natural Products. 2005 December;68(12):1720-2 Noni has long been used as a medicinal plant in Polynesia. Recently noni has become popular in the United States and other Western countries. This study was the first to isolate a special anthraquinone: 2-methoxy-1,3,6-trihydroxyanthraquinone. This anthraquinone is a strong quinone reductase inducer. It is about 40 times more active than sulphoraphane.
Chemical constituents of the fruits of Morinda citrifolia (Noni) and their antioxidant activity.
The Journal of Natural Products. 2005 April;68(4):592-5 The purpose of this study was to isolate and identify phytochemicals in noni fruits. First the phytochemicals were first extracted with methanol and then separated in a N-Butyl Alcohol -soluble fraction. The researchers isolated and identified 17 known phytochemicals and two new phytochemicals: 6-alpha-hydroxyadoxoside and 6-beta,7-beta-epoxy-8-epi-splendoside. The researchers also isolated 6 know phytochemicals for the first time from noni: borreriagenin, cytidine, deacetylasperuloside, dehydromethoxygaertneroside, epi-dihydrocornin, methyl alpha-d-fructofuranoside and methyl beta-d-fructofuranoside. The phytochemicals with the highest antioxidant activity were neolignan and americanin A.
