Saponins from Brans of Quinoa, Chenopodium quinoa WILLD. I

Grains of Quinoa, Chenopodium quinoa (Chenopodiaceae), have been used as a staple food in the Andes, South America. From brans of grains of this plant, five new saponins were isolated and their structures were elucidated as 28-O-β-glucopyranosyl esters of hederagenin 3-O-β-glucopyranosyl-(1→3)-α-ara...

Summary:Grains of Quinoa, Chenopodium quinoa (Chenopodiaceae), have been used as a staple food in the Andes, South America. From brans of grains of this plant, five new saponins were isolated and their structures were elucidated as 28-O-β-glucopyranosyl esters of hederagenin 3-O-β-glucopyranosyl-(1→3)-α-arabinopyranoside and 3-O-β-glucopyranosyl-(1→3)-β-galactopyranoside, and 28-O-β-glucopyranosyl esters of phytolaccagenic acid 3-O-α-arabinopyranoside, 3-O-β-glucopyranosyl-(1→3)-α-arabinopyranoside and 3-O-β-glucopyranosyl-(1→3)-β-galactopyranoside.
