Abstract: We selected Tectaria coadunate (kali niyuro, कालिन्युरोin Nepalese language), a very common local nutritious vegetable in Nepal, to study its phytochemical and nutritional behavior. We chose methanol and hexane as polar solvents and prepared respective extracts of its leaves and rhizomes by soxhlet extraction method. We unveiled alkaloids, polyphenols and tannins as the predominant phytochemicals. The percentage composition of different nutrition parameters (moisture, total ash, crude fat, protein, crude fiber, carbohydrate) are found to be 87.23, 1.40, 0.14, 1.76, 2.42, 6.97 in fresh leaves sample and 0, 11.04, 1.11, 13.88, 19.05, 54.93 in oven dried leaves sample respectively. The vitamin C content is around 10.49 mg/100 g of the oven dried leaves sample. The total phenolic and flavonoid contents of methanol extract of rhizomes are estimated as 186.61 mg/g (GAE) and 143.72 mg/g (QE) respectively. The zones of inhibition shown by methanol extracts of leaves and rhizomes for E. coli, K. pneumoniae and S. aureus bacteria are measured as 16, 9, 20 mm and 15, 11, 21 mm respectively in antibacterial assay. In DPPH free radical scavenging test for antioxidant activity, the IC50 values of hexane and methanol extracts of leaves and rhizomes are143.49, 150.80μg/mL and 76.32, 50.81μg/mL respectively. The presence of major chemical compounds: Decenediol<1,10>, Dodecanoic acid, Methyl stearate and Palmitic acid are confirmed by GC/MS analysis.
