Nutraceuticals from Noni – Review and Possible Extraction Technological Interventions

Morinda citrifolia L., the “noni”, an under utilised miracle plant has been used in traditional medicine for over centuries. It is reported to have more than 150 nutraceuticals. All the partsfrom theplants is foundto be useful and possess antimicrobial, anticancer, antioxidant, anti-inflammatory and cardiovascular properties. As a result of these uses Noni has gained importance in the recent year. The method of processingand extractionplay a vital role in the quality of nutraceuticals extracted. Extraction techniques used so far are basically traditional methods that are time-consuming and require relatively large quantities of solvents. In view of increased acceptance of green chemistry, there is an increasing demand for newextraction techniques with shortened extraction time, better extraction efficacy, reduced organic solvent consumption, and increased pollution prevention. This review paper gives a brief introduction to Noni, itschemical composition and traditional uses. Important nutraceuticals extracted from noni and its positive health effects have been discussed. The possibility of application of novel extraction methods like sonic assisted extraction, microwave-assisted extraction and supercritical fluid extraction for fast andefficient extractionof nutraceuticals chemicals from solid plant matrixes is also enumerated.
