Abstract: In Nagaland ~70 of population lives in rural areas and depends on forestproducts for livelihood. Being part of the biodiversity hotspot, state is richin biodiversity. The present study was an attempt made to understand thenutritional properties of 22 popular underutilized edible plants (UEP) Kohima,Phek, Tuensang districts. Results revealed moisture content of 22 studiedplants ranged between 4.8 to 88.15 g 100g, while protein content varied between 0.00269 - 0.773 g 100g with highest in Terminalia chebula (0.773 g 100g) fruit while lowest protein content was in Setaria italica (0.00269 g 100g). Total carbohydrate content was between 0.198 - 5.212 g 100g with highest in Setaria italica (5.212 g 100g)and lowest in Juglans regia (0.198g 100g). Of the 22 samples, maximumantioxidant activity was in Terminaliachebula fruits (37.49 μg ml) followed by Clerodendrum glandulosum (65.29 μg ml) leaves, Phyllanthus emblica (79.08 μg ml) fruits against Trolox (96.89μg ml). Highest total phenol content (TPC) was recorded in Terminalia chebula (53.11mg GAE g) and Rhus chinensis (43.99mg GAE g) while in other 20 crops the values varied from 0.09 - 8.44 mg GAE g. Total flavonoid content (TFC) varied between 0.004 - 43.67mg QE g with clerodendrum glandulosum (43.67 mg QE g) and Terminalia chebula (27.78 mg QE g) were found to be highest among the 22 plant samples. Findingssuggest that these underutilized edible plants should be popularized as theycan contribute to nutritional support to differentregion of the state for health improvement and cultivated them commercially to help and develop various value added local product to improvethe livelihood status of the rural population and also add to the economy ofthe state and region.
