Abstract :
In this work, four fatty acid derivatives including, methyl tritriacont17en1-oate 1, (9Z, 12Z)-ethyl octadeca-9,12-dienoate 2, stearic acid 3, and 21-acetyl tetracosanoic acid 4 were isolated from acetone extract of the stem barks of Albizia amara by chromatographic separation [TLC and CC]. The structures of the isolated compounds were established on the basis of extensive spectroscopic studies including 1D, 2DNM, and MS analysis, and compared with literature. Compound 1, 2 and 3 were reported first time from the Albizia genus and compound 4 was a new phytoconstituent isolated for the first time from plant sources.
