Acylated cyanidin 3-sambubioside-5-glucosides from the purple-violet flowers of Matthiola longipetala subsp bicornis (Sm) P. W. Ball. (Brassicaceae)

摘要

A novel acylated cyanidin 3-sambubioside-5-glucoside was isolated from the purple-violet flowers of Matthiola longipetala subsp. bicornis (Sm) P. W. Ball. (family: Brassicaceae), and determined to be cyanidin 3-O-[2-O-(2-O-(trans-feruloyl)-beta-xylopyranosyl)-6-O-(trans-feruloyl)-beta-glucopyranoside]-5-O-[6-O-(malonyl)-beta-glucopyranoside] by chemical and spectroscopic methods. In addition, two known acylated cyanidin 3-sambubioside-5-glucosides, cyanidin 3-O-[2-O-(2-O-(trans-sinapoyl)-beta-xylopyranosyl)-6-O-(trans-feruloyl)-beta-glucopyranoside]-5-O-[6-O-(malonyl)-beta-glucopyranoside]and cyanidin 3-O-[2-O-(beta-xylopyranosyl)-6-O-(trans-feruloyl)-beta-glucopyranoside]-5-O-[6-O-(malonyl)-beta-glucopyranoside] were identified in the flowers
