Meliarachins A–K: Eleven Limonoids from the Twigs and Leaves of Melia azedarach

摘要

Eleven new limonoids, meliarachins A–K (1–11, resp.), together with five known ones, were isolated from the twigs and leaves of Melia azedarach. The structures of the new compounds were elucidated on the basis of spectroscopic analysis. Compounds 4 and 8 exhibited moderate antibacterial activities against Gram-positive bacteria.
