Description | This alkaloid occurs in Garrya species and is a major constituent of G. veatchii. It
is laevorotatory with [α]27.5D - 69.01°. The crystalline hydrochloride has m.p.
2Sl-2°C (dec.); hydrobromide, m.p. 229-2300 C and the hydriodide, m.p.
222-3°C (dec.). The O-acetate has m.p. l52-3°C and yields a hydrochloride,
m.p. 258-9°C. The structure has been determined by chemical analysis and
from spectroscopic data. | References | Wiesneretal., Can. J. Chem., 30,608 (1952)
