Examinations were made on tertiai y bases contained in the tuber of Corydalis ambigua CHAM, et SCHLECHT, var. amurensis MAXIM. (Japanese name “Ezo-engosaku”), growing wild in the Hokkaido and northeastern parts of Japan, and one hind of phenolic base and four kinds of nonphenolic bases were isolated. The phenolic base was assumed to be d-corybulbine. Two of the four nonphenolic bases were identified as d-corydaline and protopine. One of the remaining two was found to be a tetrahydroberberine-type base of m. p. 144-146° and the other was a base of m. p. 194-195°. There is a fairly great difference in the bases contained in this plant and Corydalis ambigua CHAM. et SCHLECHT growing in China.
