Chemical constituents from the leaves of Aglaia odorata.

A new dammarane triterpene, 3-acetoxy aglinin C (1), and a new aglain, 10-oxo-aglaxiflorin D (2), along with five known compounds, 3-7, were isolated from the leaves of Aglaia odorata using chromatographic methods. The structures of 1 and 2 were determined on the basis of spectroscopic analyses. Bioactivities of 1-7 against AGZY 83-a (human lung cancer cell line) and SMMC-7721 (human liver cancer cell line) cells were determined.
