Abstract

The essential oil obtained from roots of different collections of Ligusticum mutellina was tested against 3rd instar armyworms, Pseudaletia unipuncta (Lepidoptera: Noctuidae), for insecticidal activity. The main compounds were isolated and their structures were elucidated using 2D-NMR techniques. Our collections contained dillapiole, ligustilide and myristicin as major compounds. The previously reported sarisan was not present, moreover its occurrence in L. mutellina should be revised based on our findings.
