Diamide Derivatives and Cycloartanes from the Leaves of Aglaia elliptica.

Chemical examination of the leaves of Aglaia elliptica led to the isolation of two new diamides, 10-O-acetyl-aglain B (1) and 4-epiaglain A (2), two known diamides, aglain A (3) and odorine (4), and three known cycloartanes (5-7). The structures of 1 and 2 were elucidated by interpretation of the spectral data.
