Background: Musa paradisiaca (Banana plant) belong to family musaceae is one of the well-known herbaceous flowering edible plants. Flower, fruit, and stem of banana plants have been used in nutritional benefit and also medicinal importance.

Objective: The aim of this study is to determine the secondary metabolites, proximate compositions, minerals, heavy metals, and anti-oxidant activity of three edible parts (flower, unripe fruit, and stem) of Musa paradisiaca.

Methods: Alkaloids and tannins content were determined by simple titrimetric method and colorimetric method used for determination of phenolics and flavonoids content. Association of Official Analytical Chemicals (AOAC) methods was used for determination of proximate compositions and content of trace elements were analyzed by atomic absorption spectrophotometer. Anti-oxidant activity was determined by 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging assay and hydrogen peroxide (H2O2) radical scavenging assay.

Results: The results indicated that three edible parts (flower, unripe fruit, and stem) of banana plant content good amount of secondary metabolites (such as alkaloids, phenolics, flavonoids, and tannins) and also primary metabolites (such as carbohydrate, protein, and fat). Banana fruit content highs amount of energy level (261.31 kcal/100g) compare the others two parts (flower, and stem). Iron, potassium, phosphorus, and calcium were found to be present in these three edible parts of banana plant. Lead was found to be presence in negligible amount and arsenic was not detected. Fifty percent of ethanolic extract of three edible parts of banana plant had showed significant scavenging activity as compared to standard ascorbic acid against the DPPH free radical scavenging assay and H202 radical scavenging assay.

Conclusion: Based on these findings, three edible parts of Musa paradisiaca can be recommended as a good source of nutrients.

Keywords: Musa paradisiaca, secondary metabolite, proximate composition, mineral, antioxidant activity, dietary supplement.
