| Abstract: | A new acylated anthocyanin was isolated from a strain of Petunia integrifolia subsp. inflata with dusky violet flowers (B1204d), and identified as malvidin 3-O-6-O-(4-O-(4-O-(6-O-(trans-caffeoyl)-β-d-glucopyranosyl)-trans-p-coumaroyl)-α-l-rhamnopyranosyl)-β-d-glucopyranoside] as a major pigment. Also, two known pigments were found in these flowers, and determined to be malvidin 3-caffeoylrutinoside and 3-p-coumaroylrutinoside. |
