Description and Uses
A hepatotoxic alkaloid of the pyrrolizidine group obtained from Crotalaria retusa and C. spectabilis, the base is laevorotatory with [α]26D - 55.7° (CHCI3). It may be characterized as the hydrochloride, m.p. 184°C ldec.); [α]28D - 38.4° (H20) and the methiodide which crystallizes from MeOH with 3 moles of solvent, m.p. 205°C (dry, dec.); [α]28D + 23.4° (MeOH). Hydrolysis with boiling Ba(OHh furnishes retronecine and monocrotic acid, C7H120 3, b.p. 145-6°C/ 18 mm which is optically inactive. This acid yields a methyl ester, b.p. 94-6°Cj 18 mm, a p-bromophenacyl ester, m.p. 78°C and a 2:4-dinitrophenylhydrazone, m.p. 95-6°C. Hydrogenation in the presence of Pt02 as catalyst yields retro_x0002_necanol and monocrotalic acid, CSH120S' m.p. 181-2°C; [α]28D - 5.33° (H20) which gives a methyl ester, m.p. 79-800 C; [α]30D - 16.2° (EtOH) and a pbromophenacyl ester, m.p. 162-3°C.
