Polyphenolic antioxidant constituents of Rosa persica
S. Zamanizadehnajarib
, S. Tahara


Abstract
2,2-Diphenyl-l-picrylhydrazyl (DPPH) radical scavenging TLC autographic assay guided fractionation of a butanolic fraction of an acetone extract of Rosa percica resulted in separation and identification of five known phenolic antioxidants for the first time. They are including three flavonoids: catechin (1), (+)-gallocatechin (2) and quercetin 3-0-β?-D- glucuronoside (3), and one condensed tannin: procyanidin B-3 (4), and one hydrolysable tannin: gallic acid 4-0-β-D-(6'-0-galloyl)-gIucopyranoside (5). The radical scavenging activity of 5 is determined by DPPH spectrophotometeric assay.

On Buds and Stipules (1899) p. 188
Sir John Lubbock, Bart. M.P.
The stem is prickly, and the frequent occurrence of the prickles, sometimes in pairs, at the base of the leaf has led to their description as stipules; for instance, by Boissier in his great ‘Flora Orientalis’
