A new flavonol glycoside from glandless cotton seeds
A new flavonol glycoside, namely quercetin 3-O-[α-d-apiofuranosyl(1-5)-β-d-apiofuranosyl(1-2)]-α-l-rhamnopyranosyl(1-6)-β-d-glucopyranoside (1), was isolated from glandless cotton seeds together with the known compounds quercetin 3-O-α-l-rhamnopyranosyl(1-2)-[α-l-rhamnopyranosyl(1-6)]-β-d-glucopyran...

| Summary: | A new flavonol glycoside, namely quercetin 3-O-[α-d-apiofuranosyl(1-5)-β-d-apiofuranosyl(1-2)]-α-l-rhamnopyranosyl(1-6)-β-d-glucopyranoside (1), was isolated from glandless cotton seeds together with the known compounds quercetin 3-O-α-l-rhamnopyranosyl(1-2)-[α-l-rhamnopyranosyl(1-6)]-β-d-glucopyranoside (manghaslin, 2), kaempferol 3-O-β-d-apiofruranosyl(1-2)-β-d-glucopyranoside (3) and kaempferol 3-O-α-l-rhamnopyranosyl(1-6)-β-d-glucopyranoside (4). It is interesting that the tetrasaccharide fragment of 1 contained both a β-apiosyl and an unusual α-apiosyl group. |
