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)-β-xylopyranosyl)-6-O-(trans-feruloyl)-β-glucopyranoside] -5-O-[6-O-(malonyl)-β-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)-β-xylopyranosyl)-6-O-(trans- feruloyl)-β-glucopyranoside]-5-O-[6-O-(malonyl)-β-glucopyranoside] and cyanidin 3-O-[2-O-(β-xylopyranosyl)-6-O-(trans-feruloyl)-β- glucopyranoside]-5-O-[6-O-(malonyl)-β-glucopyranoside] were identified in the flowers.

The hydrolysis of proanthocyanidins to anthocyanidins in n-BuOH-HCl (95:5) has been shown to be an autoxidation, the yield of anthocyanidin being critically dependent on trace metal-ion impurities.Reproducible yields of anthocyanidin may be achieved if iron(III) salts are added to the reaction medium, and a standard method of analysis of proanthocyanidins besed on use of an n-BuOH-HCl-FeIII mixture is given.The ratio of absorbance maxima of the cyanidin (550 nm) produced to near 280 nm for the original procyanidin polymer solution was ca. 3.5. Key Word Index - Procyanidin; prodelphinidin; anthocyanidin; hydrolysis; autoxidation; iron salts; analytical method.
Effects of aronia melanocarpa constituents on biofilm formation of escherichia coli and bacillus cereus

Many bacteria growing on surfaces form biofilms. Adaptive and genetic changes of the microorganisms in this structure make them resistant to antimicrobial agents. Biofilm-forming organisms on medical devices can pose serious threats to human health. Thus, there is a need for novel prevention and treatment strategies. This study aimed to evaluate the ability of Aronia melanocarpa extracts, subfractions and compounds to prevent biofilm formation and to inhibit bacterial growth of Escherichia coli and Bacillus cereus in vitro. It was found that several aronia substances possessed anti-biofilm activity, however, they were not toxic to the species screened. This non-toxic inhibition may confer a lower potential for resistance development compared to conventional antimicrobials.

Thirteen anthocyanins were isolated from the flowers of two Aeschynanthus species, A. fulgens and A. pulcher, and six cultivars, ‘Mahligai’, ‘Mona Lisa’, ‘SoeKa’, ‘Redona’, ‘Freshya’ and ‘Bravera’, and identified as pelargonidin and cyanidin 3-O-sambubiosides and their malonates, succinates, p-coumarates and caffeates, and pelargonidin 3-O-glucoside by acid hydrolysis, HR-MS and NMR. Of their anthocyanins, pelargonidin 3-O-[xylosyl-(1 → 2)-(6''-malonylglucoside)] (2), pelargonidin 3-O-[xylosyl-(1 → 2)-(6''-succinylglucoside)] (3), pelargonidin 3-O-[xylosyl-(1 → 2)-(6''-E-p-coumaroylglucoside)] (4), pelargonidin 3-O-[xylosyl-(1 → 2)-(6''-Z-p-coumaroylglucoside)] (5), pelargonidin 3-O-[xylosyl-(1 → 2)-(6''-E-caffeoylglucoside)] (6) and cyanidin 3-O-[xylosyl-(1 → 2)-(6''-succinylglucoside)] (9) were reported in nature for the first time.

Three new acylated cyanidin 3-sambubioside-5-glucosides (1-3) and one new acylated cyanidin 3-(3X-glucosylsambubioside)-5-glucoside (4) were isolated from the pale-violet flowers of Ionopsidium acaule (Desf.) Rchb., together with one known anth
