| Abstract: | In order to determine insecticidal compounds from the methanol extracts of Tephrosia purpurea bark,the active compounds were isolated by activity-guided fractionation with column chromatography and identified based on NMR(nuclear magnetic resonance) and MS(mass spectrometry) data.Slidedip method was performed to determine the insecticidal activities of each compound against Myzus persicae adults,and topical application was conducted to determine contact toxicity of each compound against the 3rd instar larva... |
