[a. G. irigenin (De Laire & Tiemann 1893, in Ber. d. Deut. Chem. Ges. XXVI. 2011), f. G. iri-din iridin 2: see genin.]
A pale yellow crystalline flavonoid, C18H16O8, obtained on acid hydrolysis of iridin, of which it is the aglycone.
1894Jrnl. Chem. Soc. LXVI. i. 47 Iridin undergoes hydrolysis when heated with dilute sulphuric acid at 80–100°, yielding d-glucose and irigenin... This substance crystallises in rhombohedra, melting at 186°. 1928Ibid. 1925 These results prove that irigenin..is consequently 5:7:3′-trihydroxy-6:4′:5′-trimethoxyisoflavone. 1960Tetrahedron Let. v. 9 The synthetic irigenin..was identical with the natural product. |
