Diseases of Quinoa (Chenopodium quinoa)

Food Reviews International, 2003
Downy mildew caused by Peronospora farinosais the most damaging disease of quinoa (Chenopodium quinoa), an ancient Andean grain crop. The disease has been reported from all areas of quinoa cultivation. In the Andean highlands, it is considered endemic. Despite the disease's wide dissemination and significant effect on quinoa crop production, little is ...

Cultivation of Quinoa (Chenopodium quinoa) in Desert Ecoregion

2020
Field experiments with the Andean grain crop, quinoa (keen-waa) were tested in three localities of United Arab Emirates at two, three and five sowing densities in 2016–2017. Four quinoa genotypes were utilized (two selected quinoa lines: ICBA-Q3 and ICBA-Q5; and two introduced quinoa genotypes: Titicaca and Amarilla Sacaca).

New Oleanane Saponins in Chenopodium quinoa

Journal of Agricultural and Food Chemistry, 2001
Six triterpenoid saponins were isolated from the seeds of Chenopodium quinoa (Chenopodiaceae). Their structures were as follows: phytolaccagenic acid 3-O-[alpha-L-arabinopyranosyl-(1' '-->3')-beta-D-glucuronopyranosyl]-28-O-beta-D-glucopyranoside (1); spergulagenic acid 3-O-[beta-D-glucopyranosyl-(1-->2)-beta-D-glucopyranosyl-(1-->3)-alpha-L ...

Physicochemical characterization of quinoa (Chenopodium quinoa) flour and isolated starch

Food Chemistry, 2019
This work studies the physicochemical properties of quinoa flour and isolated starch. Starch in the seed forms clusters rich in amylopectin that are immersed in a matrix with spherical and polygonal shapes in the submicron scale. The isolated quinoa starch is rich in Sulphur and Magnesium. The quinoa flour has a higher content of protein, carbohydrates

Occurrence of sapogenins in leaves and seeds of quinoa (Chenopodium quinoa Willd)

Journal of the Science of Food and Agriculture, 2000
Seeds of the Andean seed crop quinoa usually contain saponins in the seed coat. Saponins give a bitter taste sensation and are a serious antinutritional factor. Therefore selection of sweet genotypes with a very low saponin content in the seeds is a main breeding goal. However, selection for sweet genotypes is retarded by cross-pollination.

Nutritional quality of the protein in quinoa (Chenopodium quinoa, Willd) seeds

Plant Foods for Human Nutrition, 1992
The nutritional quality of protein in quinoa seeds has been determined by amino acid assay and by animal feeding experiments. The amino acid composition of the protein in raw quinoa and washed quinoa show similar pattern. The first limiting amino acids were the aromatic amino acids thyrosine + phenylalanine giving a chemical score of 86 for protein in ...

Two flavonol glycosides from Chenopodium quinoa

Phytochemistry, 1990
Two new flavonol glycosides from the seeds of Chenopodium quinoa have been isolated. Their structures were established as kaempferol 3-apiofuranosyl(1"'----2")rhamnopyranosyl(1""----6")galactoside and kaempferol 3-apiofuranosyl(1"'----2")rhamnopyranosyl(1""----6")galactoside.

Salt tolerance mechanisms in quinoa (Chenopodium quinoa Willd.)

Environmental and Experimental Botany, 2013
In the face of diminishing fresh water resources and increasing soil salinisation it is relevant to evaluate the potential of halophytic plant species to be cultivated in arid and semi-arid regions, where the productivity of most crop plants is markedly affected.
