Abstract: Eleven chemical compounds were isolated and purified from Capparis spinosa L.by extraction and different kinds of column chromatography. Their structures were determined on the basis of the physicochemical properties and spectral analysis as octacosane (1), daucosterol (2), 1-octacosanol (3), lacceroic acid (4), hexadecanoic acid (5), butanedioic acid (6), protocatechuric acid (7), 4-hydroxy-5-methylfuran-3-carboxylic acid (8), kaempferol-3-O-?-D-glucopyranoside (9), rutin (10) and stachydrine (11). Compounds 1, 3 and 4 were obtained from Capparis genus for the first time.

Key words: Cappairs, Capparis spinosa L, chemical constituents, flavonoid, stachydrine
