Abstract

A new acetylated anthocyanin was extracted from the red-purple flowers of Saintpaulia ‘Tomoko’ with 5% HOAc-H2O or 5% formic acid-H2O, and determined to be peonidin 3-O-[6-O-(4-O-(acetyl)-α-rhamnopyranosyl)-β-glucospyranoside] (1), by chemical and spectroscopic methods. In addition, two known acetylated cyanidin glycosides, cyanidin 3-O-[6-O-(4-O-(acetyl)-α-rhamnopyranosyl)-β-glucospyranoside] (2) and cyanidin 3-O-[2-O-(β-xylopyranosyl)-6-O-(acetyl)-β-glucopyranoside] (3), were also identified in the red-purple flowers and grayed-purple leaves of S. ‘Tomoko’, respectively. These three anthocyanins have not been reported hitherto in plant tissues in the genus Saintpaulia.
