TL;DR: In petals of Silene dioica plants, an enzyme has been demonstrated which catalyses the transfer of the arabinose moiety of UDP-arabinose to the hydroxyl group on the 2″-position of the carbon-carbon bound glucose of isovitexin.

TL;DR: Chen et al. as discussed by the authors used a thin-layer chromatographic (HPTLC) method for simultaneous quantification of vitexin, rutin, orientin, isoorientin, and vitaxin in the leaves of three different bamboo species: Phyllostachys pubescens Mazel ex H. Chen et al., and Pleioblastus yixingensis S. Chen.
Abstract: Flavonoids are the main functional compounds in a bamboo leaf extract. Because of their activity flavonoids are widely used in many of health products, cosmetics, and food supplements. A simple high-performance thin-layer chromatographic (HPTLC) method has been established for simultaneous quantification of vitexin, isovitexin, orientin, and isoorientin in the leaves of three different bamboo species: Phyllostachys pubescens Mazel ex H. de Lehaie, Phyllostachys glauca McClure, and Pleioblastus yixingensis S. L. Chen et S. Y. Chen. The method was validated for precision (expressed as the coefficient of variation, CV [%]), accuracy, sensitivity, and selectivity. Instrumental precision was found to be 0.37, 0.52, 0.39, 0.13, and 0.84% and the repeatability of the method 0.98, 0.91, 1.02, 1.04 and 0.87% for isovitexin, rutin, orientin, isoorientin, and vitexin, respectively. The accuracy of the method was determined by measurement of recovery at three different concentrations. Average recovery was 99.54% for ...

TL;DR: Two new anthraquinones were isolated from the roots of Hedyotis dichotoma along with two known plant metabolites, isovitexin and ursolic acid, which were elucidated using spectroscopic techniques.
Abstract: Two new anthraquinones, 1,4-dihydroxy-2,3-dimethoxyanthraquinone (1) and 2,3-dimethoxy-9-hydroxy-1,4-anthraquinone (2), were isolated from the roots of Hedyotis dichotoma along with two known plant metabolites, isovitexin and ursolic acid. The structures of 1 and 2 were elucidated using spectroscopic techniques.

TL;DR: The results indicate the possibility that flavonoids are utilized in not only wing coloration but also as a chemical defense compound against natural threats.
Abstract: Flavonoids in the eggs, larvae, pupae and adult butterflies of Pseudozizeeria maha were identified and quantified. Isovitexin (apigenin 6-C-glucoside) was the dominant flavonoid detected in pupae and imagines, whereas saponarin (isovitexin 7-O-glucoside) was the dominant flavonoid in larvae. Saponarin, biotransformed from isovitexin by the larvae, was found to be reconverted into isovitexin at the pupal stages. The total amounts of accumulated flavonoids differed between sexes, particularly in adults where the bodies of females had a much higher flavonoid concentration than that of the males. These flavonoids were also detected in the eggs. These results indicate the possibility that flavonoids are utilized in not only wing coloration but also as a chemical defense compound against natural threats.
