Ononis spinosa Leguminosae

Also obtained by alkaline degradation of Ononin—7-(P-D-glucopyranosyloxy)-4 -methoxy isoflavone (SM) — [5251] with boiling aqueous barium hydroxide [5486]. SM was isolated from the roots of thorny restharrow Ononis spinosa) (Leguminosae, sub-family Fabaceae) [5251,5489],... [Pg.1529]

Isol. from Baptisia spp., Centrosema spp., Dalbergia spp. and Ononis spinosa (all Leguminosae, Papilionoideae) and also Iris germanica. Yellow plates (EtOH) or needles (CgHJEtOH). Mp 235-237° (227° dec.). >NR2400000. [Pg.435]

Fig 2.1 Early contributions to the flavonoid chemistry of the Leguminosae. The isoflavone glucoside, ononin (1), first obtained from the roots of Ononis spinosa (spiny restharrow) by Reinsch in 1842. Robinin (2), a flavonol 3,7-O-glycoside from the flowers of Robinia pseudoacacia (black locust tree), first mentioned in the literature by Zwenger and Dronke in 1861. [Pg.24]
