摘要：

Delphinidin 3-O-alpha-rhamnoside, malvidin 3-O-(6 "-O-alpha-rhamnopyranosyl-beta-glucopyranoside) and the 3-O-(6 "-O-alpha-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-alpha-rhamnopyranosyl-2 "-O-beta-xylopyranosyl-beta-glucopyranosides) of petunidin and peonidin are novel compounds. (C) 2000 Elsevier Science Ltd. All rights reserved.
