Two new acylated pelargonidin glycosides, and pelargonidin 3-malonylglucoside were isolated from the pink flowers of Senecio cruentus. The structure of the main pigment was determined to be pelargonidin 3-O-(6-O-malonyl-β-d-glucopyranoside)-7-O-(6-O-(4-O-(6-O-(trans-caffey)-β-d-glucopyranosyl)-trans-caffeyl)-β- d-glucopyranoside), and the second new pigment was identified as pelargonidin 3-O-(6-O-malonyl-β-d-glucopyrano-side)-7-O-(6-O-(trans-caffeyl)-β-d-glucopyranoside). © 1995.
