| Hazard Information | Back Directory | [Description]
A quaternary furoquinolinium alkaloid also obtained from the bark of Balfourodendron riedelianum (Engler) Engler., the alkaloid is normally isolated as the
crystalline chloride, m.p. 188-1 90°C (dec.); [α]24D + 40° (c 1.2S, MeOH) which
gives an ultraviolet spectrum in MeOH with absorption maxima at 221, 247, 299
and 334 mJ.t with an inflexion at 293 mf.1. 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. | [Uses]
