    NUTRITIONAL STATUS OF Chenopodium ambrosioides GROWN IN KANGRA VALLEY
    (CSKHPKV. Palampur, 2019-07-28) SHARMA, SHIVANI; Singh, Nageswer
    In the present investigation entitled “Nutritional Status of Chenopodium ambrosioides grown in Kangra Valley” the leaf samples of Chenopodium ambrosioides collected from twelve locations of Kangra valley were evaluated for various biochemical and phytochemical constituents of quality significance. Significant variation in biochemical constituents among various Chenopodium ambrosioides collections was observed i.e. moisture (26.01 to 36.64 per cent), total ash (15.01 to 19.15 per cent), crude protein (23.18 to 31.20 per cent), crude fat (2.73 to 6.89 per cent), crude fibre (9.01 to 10.69 per cent), total carbohydrate (4.95 to 13.68 per cent), sodium (227.50 to 315.00 mg/100g), calcium (912.50 to 1025.00 mg/100g), potassium (982.50 to 1086.67 mg/100g), iron (0.64 to 0.69 mg/100g), zinc (0.11 to 0.14 mg/100g), manganese (0.05 to 0.11 mg/100g) and copper (0.13 to 0.45 mg/100g). Phytochemical constituents also showed considerable variation in the total phenols (326.33 to 489.56 mg/100g), tannins (75.16 to 195.06 mg/100g), total chlorophyll (0.87 to 1.68 mg/g), carotenoids (13.33 to 23.87 µg/g), ascorbic acid (7.25 to 17.29 mg/100g), PPO (polyphenol oxidase) activity (0.045 to 0.092 ΔOD/min), and antioxidant activity (4.53 to 9.18 µg/ml). Multi-purpose/versatile collections were identified based on cumulative rating as Dehra, Harchkiyan, Jaswan, Palampur and Daroh followed by Thural for proximate composition, mineral content and phytochemical constituents excelling in that order of preference.
