“…Quinoa also acts as a cell protector and presents an important source of antioxidants [13] due to its polyphenolic phytonutrient constituents, and therefore could be used for medicinal purposes in humans [14,15]. This gluten free pseudocereal recommended to be used as an ingredient in food such as bread, pasta or baby food and also in common diets [16], since; only effective treatment [17] for celiac disease (CD) is a life-long gluten-free diet. Despite its slightly bitter taste, quinoa flour produces acceptable gluten free baked products [18] that are high in fiber and rich in antioxidants.…”

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.

“…In recent years, the cultivation of crops such as quinoa (Chenopodium quinoa Willd.) has gained increasing attention due to the attractive nutritive value of its grains, as well as an effort to expand the number of species which contribute to human nutrition (Ruiz and Bertero, 2008;Hirose et al, 2010). The outstanding nutritional and functional properties of quinoa seeds will be promoted by the FAO in 2013 since the United Nations has declared that year as the international year of quinoa.…”

This study explored the diversity of the quinoa crop in Chile from a nutritional perspective. Nutritional properties, minerals, vitamins, and saponin content were assessed in seeds of six Chilean quinoa (Chenopodium quinoa Willd.) ecotypes grown in three main production areas with distinctive climatic and edaphic conditions: Ancovinto and Cancosa in the NorthAltiplano or High Plateau, Cáhuil and Faro in the central coastal area, and Regalona and Villarrica in the south of the country. There were significant differences (P < 0.05) in all the nutritional properties of the quinoa seeds in all three areas. Quinoa of the Villarrica ecotype showed the highest protein content (16.10 g 100 g -1 DM) and the highest content of vitamins E and C (4.644 ± 0.240 and 23.065 ± 1.119 mg 100 g -1 DM, respectively). The highest content of vitamins B1 (0.648 ± 0.006 mg 100 g -1 DM) and B3 (1.569 ± 0.026 mg 100 g -1 DM) was found in the Regalona ecotype, while the highest value of vitamin B2 (0.081 ± 0.002 mg 100 g -1 DM) occurred in the Ancovinto ecotype. Potassium was the most abundant mineral with a maximum value of 2325.56 mg 100 g -1 DM in the Cancosa ecotype. Saponin content varied from 0.84 g 100 g -1 DM in the Villarrica ecotype to 3.91 g 100 g -1 DM in the Cáhuil ecotype. Significant differences were found among the Chilean quinoa ecotypes grown under different climatic conditions; however, all the quinoa seeds exhibited a high nutritional value. These results are compatible with the genetic differences previously observed in the three geographical areas under study. Thus, if more studies are conducted to show the particular properties of quinoa from specific areas, it would be possible in the future to coin the term "controlled designation of origin" (appellation d'origine contrôlée) and add commercial value to Chilean quinoa seeds in the domestic and international markets.

Identification of cultivars is essential both in breeding and to settle cultivar disputes. The purpose of the study has been to examine cultivar identities based on absorption spectra of plant pigments and to confirm a genetic stability with SCoT and RAPD molecular markers in new Polish lines of Chenopodium quinoa Willd. Spectral analysis of pigments extracted from plant inflorescences in quinoa gives an opportunity to confirm the cultivar identity and identification of 'Faro' and 'Titicaca' cultivars and their new lines. Spectral analysis is an effective method of confirming cultivar identity and it should be used in practice for the identification of cultivars or cultivars lines in Chenopodium quinoa Willd. Analysis of molecular markers indicated by RAPD as well as SCoT technique revealed a high genetic stability of the derivative lines of 'Faro' and 'Titicaca', while variation was detected in plants representing original cultivars: banding pattern different than predominant was present in three plants of 'Titicaca' (genetic distnaces from 7.5% to 55.9%) and in a single plant of 'Faro'(genetic distance 61.2% as indicated by SCoT technique).
