Trijugin-Type Limonoids from the Leaves of Cipadessa cinerascens

摘要

Four new trijugin-type limonoids,cipatrijugins A-D(1-4),together with the known cipadesin A(5),were isolated from the leaves of Cipadessa cinerascens,and their structures were elucidated on the basis of spectroscopic and computational methods.The ability of compounds 1-5 to inhibit the growth of the A549 and K562 tumor cell lines was evaluated.
