title: Two oligostilbenes, cis- and trans-diptoindonesin B, from Dryobalanops oblongifolia.
abstract: Two oligostilbenes, cis- and trans-diptoindonesin B, have been isolated from the tree bark of Dryobalanops oblongifolia (Dipterocarpaceae). The structures and relative configurations of both compounds were determined on the basis of spectroscopic evidence, including 2D-NMR spectroscopic analysis.
