Su, B-N., Pawlus, A.D., Jung, H-A., Keller, W.J. McLaughlin, J.L., Kinghorn, A.D.
The authors report the isolation of 19 phytochemicals (non-vitamin substances in fruits and vegetables that are important for health) from the fruit of noni (M. citrifolia). Two of these phytochemicals are newly discovered, having never been known to exist anywhere prior to this study. They belong to a class known as iridoid glucosides, which are important because of their anti-inflammatory and anti-oxidant properties. One of the 17 remaining compounds, americanin A, was shown to be a potent anti-oxidant. The chemical names of each of these 19 compounds are also provided.
