Quinoa is known to be an excellent source of natural antioxidants and therefore the extract of quinoa seed was considered to have a significant anti-inflammatory activity. Two different varieties of quinoa seeds and six different solvents hexane, acetone, methanol, ethanol, ethyl acetate and water were used as solvent for extraction in the present study. Extracts from water, methanol and ethanol showed significant antioxidant and phytochemical activities. Water extract showed highest Phenol content (89.73 ± 1.74), antioxidant activity (1586 ± 41.42) and DPPH scavenging capacities (82.71 ± 0.03) compared to other solvents used for extraction. IC50 value for percentage DPPH scavenging capacities by water extract was 14.71 ± 0.02, compared to ascorbic acid (7.15 ± 0.13), which is a control. All extracts exhibit significantly high levels of flavonoid content. Ethyl acetate extract represented highest (88.41 ± 0.37) NO scavenging capacity. Lowest IC50 value (52.58 ± 0.14) for NO scavenging capacity was identified for ethanol extract compared to control (24.19 ± 3.53). Ascorbic acid used as control in both DPPH and Nitric oxide scavenging capacities measurement. Quinoa seed extracts from all six solvents found to have antimicrobial activities towards gram positive bacteria but not towards all gram negative bacteria. All extracts showed significant anti proliferative activities towards P 116 cells.
