The perchlorate crystallizes from EtOH, m.p. 21S-220°C (dec.) and the picrate has m.p. 192-3°C (dec.). A phenolic hydroxyl group and a tertiary hydroxyl group are present and the alkaloid forms an O-methyl ether which furnishes crystalline salts, e.g. the iodide, m.p. 193-4°C (dec.); [α]18D + 20° (c LIS, MeOH); the perchlorate, m.p. 200- 2°C (dec.) and the picrate, m.p. lSI-2°C.
使用Ribalinium is a naturallly occuring alkaloid from Ruta graveolens. Used as a herb.
