Albert E. Oruk and Idongesit I. Udo

Abstract

Morinda citrifolia fruit has been used mostly as drug supplement in most communities and as such needs to know the elemental compositions is necessary. Base on the analysis the following results were obtained. The seeds and the juice were subjected to analysis using standard methods proposed by Association of Analytical Chemists (AOAC, 2000) and Atomic Absorption Spectrophotometer (AAS). The results in milligrams per 100 grams (mg/100g) on the seeds were: 60.707+ 0.009 sodium, 31.017 + 0.015 calcium, 78.054 + 0.076 magnesium, 107.353 + 0.095 phosphorus, and 116.641 + 0.213 potassium while the concentration on the juice were; 37.406 + 0.008 sodium, 33.552 + 0.016 calcium, 54.389 + 0.001 magnesium,76.074 + 0.069 phosphorus and 68.246 + 0.024 potassium respectively. Comparing the result obtained from the analysis on WHO Recommended Dietary Intakes (RDI), phosphorus and potassium was significant in both the seeds and the juices. This was followed by magnesium and sodium, while calcium contained moderate amount in both samples. The results suggest that the plant is a valuable source of essential elements, and is sufficient in addressing macronutrient deficiencies. Therefore, the plant is a good dietary supplement.
