摘要：Chenopodium album belongs to family Amaranthaceae commonly known as pigweed or goose foot or bathua (in Hindi) is a weedy plant found all over world and has gained renowned popularity these days due to its high nutritional composition especially amino acids. In the present study the leaves of four Chenopodium album cultivars were analysed for the anti-nutritional composition viz. tannins, simple phenols, total phenols, phytic acid, oxalates, flavonoids, alkaloids, Trypsin Inhibitor Activity (TIA), phytic acid and phytate phosphorus using standard methods. The results of present investigation showed that the maximum total phenol, simple phenol and tannin content were in Ec1 cultivar i.e. 304.98, 101.007 and 203.91 mg GAE/100g respectively whereas minimum was present in Ec2 cultivar i.e. 224.99, 72.50 and 152.49 mg GAE/100g respectively. The TIA content ranged between 0.11-0.17 TIU/mg whereas the saponin content ranged between 0.027-0.867g/100g. The highest TIA was present in Ec2 cultivar whereas the saponin content was highest in Ec1 cultivar. The highest phytic acid content was present in Ec2 cultivar (268.33mg/100g) whereas lowest in Ec1 cultivar (238.33mg/100g). Similarly the maximum phytate phosphorus content was present in Ec2 cultivar and minimum in Ec1 cultivar. The alkaloid content in Chenopodium cultivar leaves ranged between 1.27-1.67mg/100g whereas flavonoid content ranged between 220.0-406.67mg/100g respectively. The maximum oxalate content was there in Ic1 cultivar (518.42mg/100g) and minimum in Ec1 cultivar (394.19 mg/100g) respectively. Certain anti-nutrients among these besides being an anti-nutrient also exert positive health effect especially phenolic compounds, flavonoids, alkaloids thus can also utilized for pharmaceutical purpose
