OBJECTIVETo study the chemical constituents of Adenanthera pavanina.

METHODVarious chromatographic techniques were used to isolate and purify the constituents. The structures were elucidated by chemical evidence and spectroscopic methods.

RESULTNine compounds were isolated from the 95% ethanol extract of the stems and leaves of A. pavanina and their structures were elucidated as aridanin (1), 3-[(2-Acetamido-2-deoxy-beta-D-glucopyranosyl)oxy]-16alpha-hydroxyolean-12-en-28-oic acid (2), (+)-pinitol (3), sucrose (4), (-)-butin (5), apigenin (6), isoliquiritigenin 4-methyl ether (7), oleanolic acid (8), daucosterol (9).

CONCLUSIONCompounds 1-7 were isolated from this plant for the first time.
