[Chemical constituents from leaves of Aglaia testicularis].

To study the chemical constituents from the leaves of Aglaia testicularis. The methanol extract was isolated and purified by silica gel, Sephadex LH-20 and preparative HPLC. Their chemical structures were elucidated by MS and spectral data (1H, 13C-NMR). Seven compounds were isolated from the leaves and identified as dasyclamide (1), aglamide A (2), aglamide B (3), aglamide C (4), aglamide D (5), aglaroxin A 1-O-acetate (6), and 3'-methoxyaglaroxin A 1-0-acetate (7). All compounds were isolated from this plant for the first time.
