Eight flavonoids, ugonins E-L (1-8), were isolated from the rhizomes of Helminthostachys zeylanica, and their structures were established on the basis of spectral evidence. Compounds 3-8 were evaluated for their antioxidative activity in the 1, 1-diphenyl-2-picrylhydrazyl (DPPH) assay. Compounds 6,
Three new cyclized geranyl stilbenes, ugonstilbene A ( 1), ugonstilbene B ( 2), and ugonstilbene C ( 3), and one known compound 3-hydroxyacetophenone, were isolated from the dried rhizomes of H. zeylanica. The structures of these three new compounds were elucidated on the basis of spectral analysis.
