title: Triacylated peonidin 3-sophoroside-5-glucosides from the purple flowers of Moricandia ramburii Webb.
abstract: Triacylated peonidin 3-sophoroside-5-glucosides were isolated from the purple flowers of Moricandia ramburii Webb. (Family: Brassicaceae), and determined to be peonidin 3-O-[2-O-(2-O-(trans-feruloyl)-glucosyl)-6-O-(trans-p-coumaroyl)-glucoside]-5-O-[6-O-(malonyl)-glucoside] (1), peonidin 3-O-[2-O-(2-O-(trans-feruloyl)-glucosyl)-6-O-(cis-p-coumaroyl)-glucoside]-5-O-[6-O-(malonyl)-glucoside] (2) and peonidin 3-O-[2-O-(2-O-(trans-sinapoyl)-glucosyl)-6-O-(trans-p-coumaroyl)-glucoside]-5-O-[6-O-(malonyl)-glucoside] (3), respectively, by chemical and spectroscopic methods. In addition, one known acylated cyanidin glycoside, cyanidin 3-O-[2-O-(2-O-(trans-feruloyl)-glucosyl)-6-O-(trans-p-coumaroyl)-glucoside]-5-O-[6-O-(malonyl)-glucoside] (4), was also identified in the flowers. Peonidin glycosides have not been reported hitherto in floral tissues in to Brassicaceae.
