Malnutrition and hunger is a serious global issue, however, wild fruits possess the potential of combatting it being rich in nutrients. Stereospermum chelonoides (L.f.) DC., commonly known as “Patala” in Ayurvedic text, is a large wild tree bearing edible, yet, underutilized fruits consumed by the locals in Western parts of India and neighboring countries. The present study focuses on the nutritional profile of S. chelonoides fruit along with quantification of bioactive constituents using RP-HPLC-PDA and evaluation of in-vitro anti-oxidant and, anti-microbial activity. The fruit was found rich in nutritional composition having protein (2.41 % ± 0.007), fibre (3.46 % ± 0.02) and carbohydrate (90.19 % ± 1.73) with energy value of 368.2 ± 3.94 Kcal/100g. The elemental analysis of fruit resulted in macronutrients Ca, Mg and Na and micronutrients Fe, Mn, Zn, and Cu in amounts comparable to common marketed fruits. The RP-HPLC-PDA analysis revealed the presence of six phenolic compounds in all 3 extracts made from the fruit in which highest amount are present in hydro-alcoholic extract. All the extracts exhibited potent antioxidant activity evaluated through DPPH assay and oxygen radical absorbing capacity (ORAC), with highest activity in hydro-alcoholic extract. All the analyzed extracts also exhibited potent inhibition, against four human pathogens namely Pseudomonas aeruginosa, Vibrio cholerae, Escherichia coli, and Shigella flexneri. Therefore, it is evident from the study that the fruit of S. chelonoides has immense potential as a nutraceutical supplement and may help in the management of nutrient deficiency and malnutrition among rural and tribal communities.
