摘要：

Two anthocyanins were isolated from ornamental reddish flowers of Plumeria rubra L (Apocynaceae) by a combination of chromatographic techniques. Their structures were elucidated mainly by the use of homo- and heteronuclear nuclear magnetic resonance spectroscopy and high-resolution electrospray mass spectrometry. The anthocyanin cyanidin 3-O-beta-(2"-glucopyranosyl-O-beta-galactopyranoside) (75%), has previously been isolated only from Corn us suecica (Cornaceae) fruits, while the other (20%) was identified as cyanidin-3-O-beta-galactopyranoside. This is the first report of the anthocyanins responsible for the attractive colours of the flowers of red frangipani. (C) 2011 Elsevier B.V. All rights reserved.
