The non-phenolic tertiary alkaloids from Corydalis incisa PERS., in each vegetative and reproductive phases, were investigated. Three new natural alkaloids, l-tetrahydrocorysamine, acetylcorynoline, and acetylisocorynoline, and five unknown alka1oids, TN-4, -5, -12, -21, and -23 were isolated from this plant, in addition to isocorynoline, corynoline, corycavine, and protopine. Yield of these alkaloids (Table I), indicates that variation in the content of alkaloids is attributed to the growing stage.
