Abstract

Two new furanoid diterpenes, teucjaponin A (II) and teucjaponin B (V), have been isolated from Teucrium japonicum HOUTT. together with teucvin (I) and their structures were determined on the basis of chemical and spectral data. Teucjaponin A showed antifeedant activity for Prodenia litura.
