13-cis-Crocin: a new crocinoid of saffron: 13-cis-Crocin: a new crocinoid of saffron. Speranza, Giovanna; Dada, Giuseppe; Manitto, Paolo; Monti, Diego; Gramatica, Paola (Cent. Studi Maria Branca, Milan I-20158, Italy). Gazz. Chim. Ital., 114(3-4), 189-92 (English) 1984. CODEN: GCITA9. ISSN: 0016-5603. DOCUMENT TYPE: Journal CA Section: 17 (Food and Feed Chemistry) A new crocinoid isolated from saffron was shown to be a stereoisomer of crocin [42553-65-1], i.e. 13-cis-crocin [91740-80-6]. In the light of this finding, the old question of the natural occurrence and structure of neocrocins in saffron is discussed.
