Determinations of Nutritional Compositions and Antioxidant Activity in the Leaves of Morinda citrifolia Linn

Abstract

The leaves of Morinda citrifolia Linn. collected from Mandalay University Campus, Mahaaungmyay Township, Mandalay Region were selected for reliminary phytochemical screening, elemental analysis, determinations of nutritional compositions and antioxidant activity. The phytochemical compositions of the sample was investigated using test tube method. The mineral elements present in the sample were determined using Energy Dispersive X-ray Fluorescence (EDXRF spectrometer. The presence of proteins in the sample was investigated by qualitative tests. The nutritional values of the sample were also determined. The antioxidant activity of the sample was tested by DPPH (1,1 diphenyl-2-picryl-hydrazyl) assay using ascorbic acid as standard
