Maackia amurensis, commonly known as theAmur maackia, is a species of tree in the familyFabaceae that can grow 15 metres (49 ft) tall. The species epithet and common names are from theAmur River region, where the tree originated; it occurs in northeastern China, Korea, and Russia.[1]
Amur maackia tolerates severe dryness, cold and heavy soils. More interesting than the summer flowers are the unfolding buds in spring which appear silvery and showy like flowers with frost on them.
Named for Richard Otto Karlovich Maack (Richard Maack), a 19th-century Siberian explorer who discovered the tree in the Amur River region on the border between Siberia and China.
The isoflavonesdaidzein,retusin,genistein andformononetin and the pterocarpansmaackiain andmedicarpin can be found inM. amurensis cell cultures.[2]
Thequinolizidine alkaloids tetrahydroleontidine and 11-epileontidane have been isolated from the species (their only natural source so far).[3]
