抄録

Examinations were made on the nonphenolic tertiary bases in the rhizome of Corydalis ambigua CHAM. et SCHLECHT. var. amurensis MAXIM. (Japanese name, Ezoengosaku) and base (VI), C₂₀H₂₁O₄N, m.p. 171-172°, (possibly sinactine), and dl-tetrahydropalmatine were isolated. Presence of canadine was suggested from the result of thin-layer chromatography. Base (I), isolated earlier, was identified by mixed fusion with d-corybulbin, kindly supplied by Dr. Manske. Examinations were also made on quaternary bases in this rhizome and dehydrocorybulbine, dehydrobase (II), dehydrocorydaline, and palmatine were isolated as the protoberberine-type bases. All the alkaloids found in the rhizome of Corydalis ambigua CHAM. et SCHLECHT. var. amurensis MAXIM, are listed in Table I.
