Ecdysteroids of Quinoa Seeds (Chenopodium quinoa Willd.)

Journal of Agricultural and Food Chemistry, 2001
Quinoa (Chenopodium quinoa) is a hardy and nutritious Latin American pseudo-cereal. Studies on the seeds led to the isolation of five ecdysteroids using column chromatography. Their structures were determined as ecdysterone, makisterone A, 24-epi-makisterone A, 24(28)-dehydromakisterone A, and 20,26-dihydroxyecdysone by spectroscopic methods.

Stability of quantitative traits in quinoa (Chenopodium quinoa)

TAG Theoretical and Applied Genetics, 1996
The stability of various descriptive characters was studied over a 5-year period in 14 lines of quinoa (Chenopodium quinoa Willd.) to determine the most appropriate time in a breeding programme when selection for these characters could be performed, and which lines could serve as potential parents. Various measures of stability were employed to analyse

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.

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 ...

Triterpene Saponins from Debittered Quinoa (Chenopodium quinoa) Seeds

Journal of Agricultural and Food Chemistry, 2002
Twelve triterpene saponins have been isolated from the debittered seeds of quinoa (Chenopodium quinoa), and their structures were characterized on the basis of hydrolysis and spectral data, especially NMR evidence. Among them, three compounds, including 3-O-beta-D-glucuropyranosyl oleanolic acid (1), 3-O-beta-D-glucopyranosyl-(1-->3)-alpha-L ...

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 ...

Breeding quinoa (Chenopodium quinoa Willd.): potential and perspectives

Molecular Breeding, 2014
Quinoa (Chenopodium quinoa Willd.) originated in the Andean region of South America; this species is associated with exceptional grain nutritional quality and is highly valued for its ability to tolerate abiotic stresses. However, its introduction outside the Andes has yet to take off on a large scale.
