[Studies on chemical constituents from stems and leaves of Adenanthera pavanina].

OBJECTIVE

To study the chemical constituents of Adenanthera pavanina.

METHODS

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

RESULTS

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).

CONCLUSIONS

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