1914Chem. Abstr. VIII. 336 A violet sol[utio]n..is hydrolyzed..giving 2 mol[ecule]s glucose and cyanidin chloride, C16H13O7Cl. Ibid. 3422 If quercetin be reduced at 35° instead of at 0°, a small quant[ity] (0·5–4·0%) of cyanidin is formed. 1939Thorpe's Dict. Appl. Chem. (ed. 4) III. 512/1 Cyanidin is the most common and widely distributed of the anthocyan pigments of plants, and occurs naturally in the form of various glycosides. 1966J. B. Harborne in T.
