dc.descriptionThe present study was carried out at College of Horticulture and Forestry, CAU, Pasighat, Arunachal Pradesh to investigate the unknown potential of underutilized vegetables species in terms of nutritional and antinutritional aspects with the aim to build up the nutritional security and to bring out a standard food composition database. The present analysis was carried out for characterization and estimation of nutrients content to acqiure information on its morphological characteristic, nutritional and antinutritional compositions of fifty (50) different traditional vegetable species of North East India.en_US
dc.description.abstractBased on fruit morpholgical attributes, Canavellia gladiata recorded highest fruit length (25.54 ± 0.09 cm) followed by Leucaena leucocephala (12.07 ± 0.49 cm). The maximum fruit width (6.60 ± 0.22 cm) and weight (183.3 ± 2.05 g) was observed in Sechium edule. Based on leaf morphological attributes, Colocasia esculenta was recorded highest leaf size and weight under study. In case of nutritional composition, Solanum macrocarpum was found to be good source of total carbohydrates (9.54 ± 0.081 %), Riboflavin (81.19 ± 0.002 mg/ 100 g) and vitamin C (120.87 ± 0.125 mg/ 100 g). Momordicha cochinchinesis exhibited higher methionine (24.9 ± 0.046 µg/g), soluble protein (1.47 ± 0.054 g/100 g), crude protein (5.69 ± 0.249 %), Vitamin A (345.60 ± 0.023 mg/100 g), Vitamin B1 (0.08 ± 0.081), calcium (2.26 ± 0.205 %) and magnesium (1.30 ± 0.698 %). Momordicha muricata was recorded rich in cellulose content (262.33 ± 0.020 mg/100 g), total chlorophyll (10.51± 0.060 mg/ 100 g) and iron (10.67 ± 0.016 mg/ 100 g). Cyphomandra betacea was found good in reducing sugar (2.57± 0.014 %), total carotenoid (10.87 ± 0.040) and total flavonoid (75.19 ± 0.069 mg/100 g). Solanum indicum (45.94 ± 0.012 %) showed good source of anti oxidant activity. Whereas in case of leafy vegetable species, cellulose content (275.33 ± 0.101mg/ 100g), vitamin A (263.33 ± 0.005 mg/100 g) and antioxidant (59.57 ± 0.000 %) observed in Clerodendrum colebrookianum. Sauropus androgynus was found rich in total free amino acid (996.67 ± 0.052 mg/100 g), soluble protein (2.75 ± 0.062 g/100 g), thiamine (0.10 ± 0.011 mg/ 100 g), vitamin C (87.57 ± 0.266 mg/100 g) and total chlorophyll (71.34 ± 0.453 mg/ 100 g) where as Sida acuta was recorded rich in reducing sugar (1.95 ± 0.004 %) and calcium (2.80 ± 0.170 %) while, Colocasia esculenta was recorded maxiumum for starch (1231.1 ± 0.052 mg/ 100 g) and sodium (28.7 ± 0.67 ppm). Maximum radical scavenging activity content was observed in Clerodendrum colebrookianum (59.57 ± 0.00 %) followed by Hibiscus sabdariffa (55.65 ± 0.00 %). Based on Antinutrtional factors, Canavellia gladiata was recorded maximum phenols (507.22 ± 0.004 mg/ 100 g). Highest tannin (95.55 ± 0.052 mg/100 g) and cynogen (1.40 ± 0.001 mg/ 100 g) were observed in Cyphomandra betacea. Solanum torvum recorded highest phytic acid (5.62 ± 0.006 mg/100 g) and Momordicha muricata recorded higher total alkaloid (67.90 ± 0.005 mg/100 g). Based on leafy vegetable species, Eryngium foetidum was found highest for total phenol (733.33 ± 0.004 mg/ 100 g). Maximum tannins (97.57 ± 0.003 mg/ 100 g), phytic acid (5.23 ± 0.006 mg/ 100 g), cyanogen (2.00 ± 0.003 mg/ 100), oxalate (374.0 ± 0.993 mg/ 100 g) and alkaloid (75.18 ± 0.284 mg/100 g) were found in Houttuynia cordata, Spilanthes acmella, Diplazium esculentum, Colocasia esculenta and Solanum spirale respectively. The result indicated that all the fruit vegetable and leafy vegetable species possessed varying in nutritional and antinutritional compositionsen_US
