Two new lupin alkaloids, (-)-N-(2-oxopyrrolidinomethyl)cytisine and (-)-N-(N-acetylaminomethyl)cytisine, were isolated together with 9 known alkaloids from Chinese Maackia hupehensis which grows in the south of China. This report describes the isolation and structural determination of eleven alkaloids (including the two new ones) from M. hupehensis, and a comparison of its alkaloidal constituents with those of Japanese Maackia plants. The alkaloidal constituents of M. hupehensis were shown to be comparable to those of the southern species of Japanese Maackia plants, accumulating lupinine-type, cytisine- and anagyrine-type alkaloids but no sparteine-type alkaloids.
