| Abstract | ||||
| Phytochemical constituents were separated and identified at the length ethanol extracts of leaves of Lantana. Lantana camera 8. seeds of Cumin, Cuminum cyminum and Golden shower, Cassia fistula. It is clear that, Cumin extract contained high amounts of carbohydrates, glycosides and volatile oil while flavonoides, sterols and triterpenes recorded moderate amounts. On the other hand, phenolic glycoside and cardic glycoside were detected in slight amounts, while tanins and saponin were found in trace amounts in cumin seeds. With respect of Lantana extract. it contained moderate amounts of carbohydrates, glycosides, flavonoides, volatile oil and phelonic glycoside, low amounts of sterols, triterpenes, tannins, cardic glycoside, anthraquinone and alkaloids and trace amounts of saponins. As for Golden shower, its screening showed high amounts of carbohydrates and glycosides, moderate amounts of tanins, low amounts of sterols, triterpenes. alkaloids. saponins & flavonoides and trace amounts of volatile oil. The efficiency of ethanol extract from Cumin, Golden shower and Lantana plants as expressed in LCSO and LC90 values against adults of Aphis gossypii Glover. The ethanol cumin extract which gave 82% mortality at 1.50 mglcm concentration had the best toxic effect. The extracts obtained from the three plants showed clear insecticidal activity against the tested pest. | ||||
