記事区分：原著Methanol extracts were prepared from 18 woody plants. These extracts were evaluated by a choice paper disk bioassay for antifeedant activity by choice paper disk bioassay against subterranean termite workers, Reticulitermes speratus (Kolbe). The methanol extract of resak showed the strongest antifeedant activity against the termites of in all tested extracts. This extracts was chromatographed by silica gel column chromatography. Bioassay-directed fractionation led to the isolation and identification of bridge stilbenoid trimers-vaticanol A (1), vaticanol E (2), vaticanol G (4) and tetramer-vaticanol B (3). All of the isolated compounds showed antifeedant activity against R. speratus. From a comparison of their molecular bases, their insect antifeedant activity was similar to their monomer of them, resveratrol.
