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.
