[1874O. Schmiedeberg in Arch. f. exper. Path. u. Pharm. III. 24 So bildet sich ein schön krystallisirender Körper, den man in Analogie mit dem Sapogenin Digitogenin nennen kann.] 1915Chem. Abstr. IX. 1336 Genin, C21H30O5, wartlets from 15 parts of b.96% alc. 1925Jrnl. Chem. Soc. CXXVIII. i. 1295 The genin is converted by cold, concentrated hydrochloric acid into ‘dianhydrogitoxigenin’, identical with digitaligenin from ‘Digitalinum verum’. 1927Jrnl. Biol. Chem. LXXIV. 789 The toxicities of the unhydrogenated ‘genins’ were of themselves not of the highest order. 1938Thorpe's Dict. Appl. Chem. (ed. 4) II. 381/1 All these drugs are non-nitrogenous glycosides of plant origin yielding on hydrolysis various sugars and a number of structurally similar aglycones or ‘genins’. 1959L. F. & M. Fieser Steroids i. 4 The glycoside of which digitogenin is the aglycone, or genin, is a saponin. 1964C. W. Shoppee Chem. Steroids (ed. 2) v. 367 Four aglycones: genin B, C21H30O4, genin D, C21H30O5, genin E, C21H30–32O5 and genin F, C21H34O5, isolated from D. grandiflora.., are probably digitenols. |
