Abstract: Major nutritional components as well as calorific values were estimated for nine non- conventional wild leafy vegetables traditionally used by various tribal communities of Nagaland. Different plant types were covered in the study viz herb – Eryngium foetidum, Polygonum microcephalum; shrub – Gentum gnemon, Rhynhotechum ellipticum, Zanthoxylum oxyphylum, Zanthoxylum acanthopodium, Skimmia arborescens, Lycianthus pachypetala and tree – Rhus semialata. Crude protein contents were very impressive in the range of 11.65% in S. arborescens to 28.54% in E. foetidumI. All the species were very rich in total mineral in the form of ash content which varies from 7.0% in P. microcephalum to 19.69% in S. arborescens. Crude fibre were found in apparently highamount and varied from 12.50% in Z. oxyphylum to 26.59% in G. gnemon. Total carbohydrate and lipid content were comparatively low with limited variability. Calorific value exhibited wide variability n the range of 98.21 K cal/100 gm in S. arborescens to 168.44 K cal/100gm in G. gnemon
Keywords: Non-conventional food plants, crude protein, carbohydrate, lipid, crude fibre, ash content, calorific value.
