ABSTRACT
<p><b>OBJECTIVE</b>To study the chemical constituents of Adenanthera pavanina.</p><p><b>METHOD</b>Various chromatographic techniques were used to isolate and purify the constituents. The structures were elucidated by chemical evidence and spectroscopic methods.</p><p><b>RESULT</b>Nine 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).</p><p><b>CONCLUSION</b>Compounds 1-7 were isolated from this plant for the first time.</p>
