A Quantitative Comparison of Phytochemical Components in Global Noni Fruits and Their Commercial Products.
Deng S, West BJ, Jensen J.

An analytical method was developed to measure and compared characteristic components in 7 noni fruits and 13 commercial fruit juices originating from the Caribbean, Central America, the Central and South Pacific, and Asia. Scopoletin, rutin, quercetin, and 5,15-dimethylmorindol were detected in all the samples, although at varying concentrations. This variation suggests that efficacy and safety tests conducted with one commercial source of noni juice may not be applicable to all others.
