Abstract:
Herein, we report the occurrence of four new compounds in ethanolic extract of Albizia coriaria
Welw ex. Oliver leaves along with other compounds previously reported in this species. The
compounds were isolated and characterized using column chromatography, Fourier Transform
Infrared (FTIR) and gas chromatography/mass spectrometry. FTIR spectrum of the extract showed
phenolic O−H stretching (3362.30 cm-1), C=O (1660.08 cm-1), C−O stretching (1369.46 cm-1 and
1319.00 cm-1) and C−N stretch (1072.44 cm-1) which confirmed the presence of alcohols, carboxylic
acids and nitrogen-containing compounds. Oleanolic acid (1), oleanolic acid acetate (2), pterin-6-
carboxylic acid (3), undecanol (4), betulinic acid (5), betulin (6) and benzyl alcohol (7) were
tentatively identified in the extract. Compounds 1-4 are being reported for the first time in Albizia
coriaria.
