Introduction: Borail Hills Range of Assam State of India has an enormous variety of tuber crops including aroids are important for the ethnic people for their regular dietary supplements. During scarcity of major cereal rice, the tubers play a major role in the regular diet of the ethnic groups like Dimasas, Zeme Nagas, Hmars, Hrangkhols, Biates, Kukis, Sakacheps, Vaipheis and Pnars. Aim: Quantification of the nutritional (viz. Carbohydrate, Protein, Total Fat, Crude fibre and Calorific value); nutraceutical (viz. Total mineral content, phenol content, antioxidant activity, flavonoid and the ascorbic acid); anti-nutritional (oxalates/ammonium oxalates) properties and also microelement (viz. Ca, Fe and Zn) of upland edible aroids. Methodology: Collection of the edible aroid tubers from the study area was followed by preparation of passport data and obtained Indigenous Collection numbers from Indian Council of Agricultural Research-National Bureau of Plant Genetic Resource (ICAR-NBPGR), New Delhi. Tuber samples were dried and ground to moisture-free powder for phytochemical analysis for nutritional, anti-nutritional, neutraceutical and micronutrient quantification were done. Result: A total of 27 numbers of cultivar and wild edible aroids belongs to 11 species and variability within them was analyzed phytochemically. Phytochemical analyses were broadly categorized and tabulated into nutritional property estimation, nutraceutical and anti-nutritional property estimation and microelement quantification. Conclusion: After phytochemical analysis, five nutritionally and nutraceutical superior Colocasia esculenta variants were selected (IC-0631527, 0631529, 0631536, 0631544 and 0631546) emphasizing higher calorific value and also lower anti-nutritional properties. All the selected superior germplasm were multiplied for field trial leading to agro technique development for upland cultivation.
