Effect of phytochemical and nutritional analysis of Cordia myxa and Cordia dichotoma from Dera Ismail Khan, Pakistan
Wild edibles fruits are nutritionally known as well-balanced food and have made major contribution to people’s diet. The present study was designed to analyze the proximate, mineral, antioxidant, phytochemical, organoleptic and morphological examination of the selected wild edible fruit plants (WEFPs) (Cordia myxa and Cordia dichotoma) of Dera Ismail Khan. The selected WEFPs were examined for minerals by atomic absorption spectrophotometry, antioxidants by 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay and proximate including crude fats by soxhlet assembly, proteins by Kjeldahl method and ash content by muffle incineration, respectively. The proximates were determined using standard AOAC method. The results of proximate composition revealed that carbohydrate contents of C. dichotoma were 88.35% and C. myxa were 53.79%. In addition, copper levels in C. myxa and C. dichotoma were determined to be 525.00 and 477.70 mg/kg of dry weight, respectively. Following that, we found significant free radical scavenging activity of C. myxa (IC50 46.75 μg/mL) and the highest total phenolic content was reported in C. myxa (33.41mg GAE/g) and C. dichotoma (19.59 mg GAE/g), while overall total flavonoids were 0.463 mg QE/g in both fruits. These underutilized food sources with high levels of macronutrients, trace elements and antioxidants as well as potential health benefits, increase their relevance in both traditional and modern diets.
