| Description | Corydalis ochotensis yields this alkaloid as an amorphous yellow-brown substance
furnishing a crystalline methiodide, m.p. 225°C (dec.); [αl 22
D + 49.2° (c 0.2,
MeOH). The ultraviolet spectrum of the free base in MeOH has two absorption
maxima at 226 and 287 mJi. When hydrogenated over Pd-C it yields a non_x0002_crystalline dihydro derivative with [α] 22
D+ 112°. The dihydromethine is,
however, crystalline, with m.p. 92°C. | | References | Manske., Can. J. Res., 16B, 81 (1938)
