Abstract
Three anthocyanins were isolated from the red flowers of chenille plant, Acalypha hispida Burm. (Euphorbiaceae) by a combination
of chromatographic techniques. Their structures were elucidated mainly by homo- and heteronuclear nuclear magnetic
resonance spectroscopy and electrospray mass spectrometry, and supported with complete assignments of 13C NMR resonances.
The novel pigment, cyanidin 3-O-(200-galloyl-600-O-a-rhamnopyranosyl-b-galactopyranoside) (5%), contains the disaccharide robinoside.
The other anthocyanins were identified as cyanidin 3-O-(200-galloyl-b-galactopyranoside) (85%), and cyanidin 3-O-b-galactopyranoside
(5%). Anthocyanins acylated with gallic acid have previously been identified in species from the families
Nymphaeaceae and Aceraceae, and tentatively in Abrus precatorius (Leguminosae).
