irigenin Chem.
(aɪrɪˈdʒɛnɪn)
[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.
| 1894 Jrnl. 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°. 1928 Ibid. 1925 These results prove that irigenin..is consequently 5:7:3{p}-trihydroxy-6:4{p}:5{p}-trimethoxyisoflavone. 1960 Tetrahedron Let. v. 9 The synthetic irigenin..was identical with the natural product. |
