Abstract

Coumaran (2, 3-dihydrobenzofuran), a secondary metabolite of Cyperus nipponicus, inhibits the feeding of polyphagous insects. This secondary metabolite is regarded as one of the defensive systems of the Cyperaceae. A number of naturally occurring benzofurans that differ in their substitution pattern and oxidation state have been investigated for their ability to inhibit insect feeding by a bioassay with the common cutworm (Spodoptera litura F. ...
