Carbon-13 NMR studies of flavonoids. III. Naturally occurring flavonoid glycosides and their acylated derivatives
TL;DR: In this article, 13 C NMR spectra for a variety of flavonoid glycosidcs are presented and analyzed, and evidence is presented which demonstrates that 13 C nMR spectroscopy is a valuable technique for distinguishing the sites of methylation, glycosylation and acylation in glycoiides.

[Medicinal Lamiaceae with antioxidant properties, a potential source of rosmarinic acid].
TL;DR: Hydroalcholic extracts from four native medicinal Lamiaceae, Lycopus europaeus L., Melissa officinalis L., Origanum vulgare L. and Prunella vulgaris L. have shown significant antioxidative activities, by free radical scavenger effect on DPPH, compared with those of Rosmarinus officinal is L. extracts.

Perchloric acid enhances sensitivity and reproducibility of the ferric-xylenol orange peroxide assay.
TL;DR: The ferrous oxidation in xylenol orange (FOX) assay for hydroperoxides suffers from very narrow pH optimum in the range 1.7-1.8, and substitution of perchloric for the sulfuric acid resulted in a lowering of the optimum pH of the assay to 1.1, a decreased dependence of the absorbance of the ferric-xylenl orange complex on acid concentration and decreased sensitivity to added compounds.
