A new triterpene saponin from Chenopodium ficifolium.
The new triterpene saponin 3-O-beta-D-glucopyranoside, 28-beta-D-glucopyranosyl-(1-->2)-beta-D-glucopyranosiduronic acid oleanolate was isolated from the roots of Chenopodium ficifolium. The known compounds stigmasterol-3-O-glucoside and 3-O-beta-D-glucopyranosiduronic acid, 28-beta-D-glucopyranosyl oleanolate were also isolated. The latter compound, oleanolic acid, beta-sitosterol and its gluc...
متن کاملTandem mass spectrometric analysis of a mixture of isobars using the survival yield technique.
Collision induced dissociation tandem mass spectrometry experiments were performed to unequivocally separate compounds from an isobaric mixture of two products. The Survival Yield curve was obtained and is shown to consist in a linear combination of the curves corresponding to the two components separately. For such a mixture, a plateau appears on the diagram in lieu of the continuous decrease ...
متن کاملDistribution of minerals in quinoa (Chenopodium quinoa Willd.) seeds.
The distribution of minerals in quinoa (Chenopodium quinoa Willd.) seed was examined using energy dispersive X-ray microanalysis (EDX) in combination with scanning electron microscopy (SEM). Phosphorus, K, and Mg coincided in localization in embryonic tissue. Since phytin globoids have been known to localize in protein bodies in embryonic cells of quinoa seed, it is thought that P is attributed...
متن کاملThe Worldwide Potential for Quinoa (Chenopodium quinoa Willd.)
Quinoa is a highly nutritious food product, being cultivated for several thousands years in South America, with an outstanding protein quality and a high content of a range of vitamins and minerals. Other positive aspects of quinoa are the saponins found in the seed hull and the lack of gluten. Quinoa is one of the main food crops in the Andean mountains, but during recent times there has been ...
متن کاملQuinoa (Chenopodium quinoa Willd.): composition, chemistry, nutritional, and functional properties.
Quinoa (Chenopodium quinoa Willd.), which is considered a pseudocereal or pseudograin, has been recognized as a complete food due to its protein quality. It has remarkable nutritional properties; not only from its protein content (15%) but also from its great amino acid balance. It is an important source of minerals and vitamins, and has also been found to contain compounds like polyphenols, ph...
