    The chemical constituents and insecticidal activity of the pods of <i>Senna italica</i> (Caesalpiniaceae, Fabaceae) were investigated. From the chloroform extract of pods, physcion, chrysophanol, chrysophanol-10,10′-bianthrone, chrysophanol-physcion bianthrone and chrysophanol-isophyscion bianthrone, were isolated and characterized using different spectral methods. The GC-MS of the n-hexane extract revealed that the major chemical constituents of the oil were 2,6,-di-sec-butylphenol (36.69 %), di-n-octylphthalate (12.06 %), eicosane (5.46 %), tetratriacontane (4.87 %) and 2,2'-methylenebis[6-(1,1-dimethyl)-4-methylphenol (4.18 %). The n-hexane extract showed potent insecticidal activity (100 %) against <i>Callosbruchus analis</i> F. This study suggests that<i> S. italica</i> pods cannot be a source of sennosides but for other bioactive compounds.
