Citação: Cabrita, Luis; Frøystein, Nils Åge; Andersen, Øyvind M. (2000) - Anthocyanin trisaccharides in blue berries of Vaccinium padifolium. Food Chemistry. ISSN 0308-8146. 69:1, p. 33-36
Resumo: Delphinidin 3-O-alfa-rhamnoside, malvidin 3-O-(6''-O-alfa-rhamnopyranosyl-beta-glucopyranoside) and the 3-O-(6''-O-alfa-rhamnopyranosyl-2''-O-beta-xylopyranosyl-beta-glucopyranosides) of cyanidin, petunidin and peonidin were isolated by various chromatographic techniques from the edible berries of Vaccinium padifolium. Their complete structures were elucidated mainly by one- and two-dimensional nuclear magnetic resonance spectroscopy. Together they account for 7% of the anthocyanin content in this species. No anthocyanidin 3-triglycoside, 3-rutinoside or 3-rhamnoside had previously been found in the genus Vaccinium. The 3-O-(6''-O-alfa- rhamnopyranosyl-2''-O-beta-xylopyranosyl-beta-glucopyranosides) of petunidin and peonidin are novel compounds.
