“…cis ‐Coumaryl anthocyanins are reported to elute at significantly shorter retention times than their trans isomers on reverse‐phase HPLC (Luo et al ., 2007) and to show a slight shift to longer wavelength (2–3 nm) in their UV adsorption at c . 530 nm (Yoshida et al ., 1990; Tatsuzawa et al ., 2008). Such behaviour was shown by the isomeric pairs of anthocyanins in our samples.…”

“…Reports of the presence of cis ‐coumaryl ester substituents in anthocyanins are not common (Yoshida et al ., 1990; Tatsuzawa et al ., 2008) but these compounds have been reported previously in A. thaliana seedlings grown under high‐sucrose, low‐phosphate stress (Luo et al ., 2007). Trans to cis isomerization of anthocyanin coumaryl esters may be effected by sunlight (Yoshida et al ., 1990) and the relatively high light intensities (440 µmol m −2 s −1 ) used in these experiments may have contributed to the observation of these compounds. The cis/trans isomerism of sinapoyl esters in anthocyanins does not seem to have been reported.…”

Summary• High-temperature, low-light (HTLL) treatment of 35S:PAP1 Arabidopsis thaliana over-expressing the PAP1 (Production of Anthocyanin Pigment 1) gene results in reversible reduction of red colouration, suggesting the action of additional anthocyanin regulators. High-performance liquid chromatography (HPLC), liquid chromatography mass spectrometry (LCMS) and Affimetrix ® -based microarrays were used to measure changes in anthocyanin, flavonoids, and gene expression in response to HTLL.• HTLL treatment of control and 35S:PAP1 A. thaliana resulted in a reversible reduction in the concentrations of major anthocyanins despite ongoing over-expression of the PAP1 MYB transcription factor. Twenty-one anthocyanins including eight ciscoumaryl esters were identified by LCMS. The concentrations of nine anthocyanins were reduced and those of three were increased, consistent with a sequential process of anthocyanin degradation. Analysis of gene expression showed down-regulation of flavonol and anthocyanin biosynthesis and of transport-related genes within 24 h of HTLL treatment. No catabolic genes up-regulated by HTLL were found.• Reductions in the concentrations of anthocyanins and down-regulation of the genes of anthocyanin biosynthesis were achieved by environmental manipulation, despite ongoing over-expression of PAP1. Quantitative PCR showed reduced expression of three genes (TT8, TTG1 and EGL3) of the PAP1 transcriptional complex, and increased expression of the potential transcriptional repressors AtMYB3, AtMYB6 and AtMYBL2 coincided with HTLL-induced down-regulation of anthocyanin biosynthesis.• HTLL treatment offers a model system with which to explore anthocyanin catabolism and to discover novel genes involved in the environmental control of anthocyanins.

“…In order to determine the sequence of monosaccharides, a series of 1D NOE experiments may he camed out in a sequential manner by presaturation of each of the proton resonances (Bae et al, 1994;Chen et ( I / . , 1993;Glaljgen et al, 1992;Hamburger et al, 1992;Inose et al, 1991;Kitagawa et al, 1993;Kuang et al, 1991;Lutterbach et ul., 1993;Matsumoto et al, 1994;Mizuno et ul., 1990a, b;Rockenbach et al, 1992;Satoh et al, 1994;Shoyama et al, 1990;Siddiqui et al, 1992;Tsurumi et al, 1992;Yamamoto et al, 1993a.b;Yoshida et al, 1990). However, this strategy can be misleading when NOES, correlated with an anomeric proton, appear at a chemical shift with two or more different hydrogens.…”

cyanidin 3-O-β-galactopyranoside were isolated from the red flowers of Camellia saluenensis. Out of seven anthocyanins, cyanidin 3-O-(6-O-(Z)-p-coumaroyl-β-glucopyranoside)-5-O-β-glucopyranoside was found to be isolated from the red flowers of genus Camellia for the first time. The floral distribution of anthocyanin composition was also determined by HPLC analysis between C. saluenensis and C. pitardii var. pitardii.
