Isolation and characterization of aliphatic constituents from cressa cretica aerial parts

الملخص EN

A cyclopentyl derivative, an aliphatic ester and four carbonyl compounds have been isolated from the aerial parts of Cresses cretic and the structures of all these new phytoconstituents have been characterized as 26-cyclopentyl hexacosane (criticize), 4?-methyl hexa-5¢-enoyl-n-tetracosa-17-ol-1-oate (cressatetracosanoate), n-nonacosa-6-one-1-oic (cressanonacontanoic acid), tetratriaconta-29-one-1-oic acid (cressatetratriacontanoic acid), 25-methyl-n-triacont-3-one-25-ol acid (cressatriacontanone) and a-26- octadeca-hydronaphthacenyl-n-pentacosa-3-one (cressanaphthacenone) on the basis of spectral data analyses and chemical evidences.
