Abstract

The composition of noni (Morinda citrifolia) products has been investigated. TLC profiles of several commercial juices and capsules were compared. 3-Methyl-1,3-butanediol was identified as a typical marker in noni juices. The presence of sorbic acid (E200) was detected in one juice declared as additive free. Quantitative data have been obtained by HPLC-MS. A method for the quantification of characteristic noni constituents, such as iridoid glucosides, scopoletin, rutin, fatty acid glucosides, and anthraquinones, was developed and validated. The separation was performed on a C18 column with a gradient of acetonitrile in water containing 0.1% formic acid. Detection was carried out with ESI-MS in the negative ion mode. Significant differences were observed between the products. Asperulosidic acid, deacetylasperulosidic acid, and rutin were present in all samples analyzed, but their concentrations differed considerably between the products. Fatty acid glucosides, noniosides B and C, were present in capsules and most juices. Scopoletin was mainly found in juices. The anthraquinone alizarin, which has been reported from roots and leaves, was not detected in the samples investigated.
