| Abstract: | According to the guidance of bioactivity assaying and using silica column chromatography,a compound having high antifeeding activity to the tested insect Pieris rapae L.is isolated from the ethanol extract of the leaves of Sabina vulgaris Ant..Its molecular structure is identified to be podophyllotoxin,a known compound,by UV,IR,MS and 1H-NMR.It is also found that the podophyllotoxin has antifeeding activity in higher concentrations and has stomach poisionous activity in lower concentrations to the 5 instar larva of Pieris rapae L.. |
