New bioactive aromatic compounds from Vismia guianensis

Phytochemistry, 2000
Five benzophenones, vismiaguianones A-E, and two benzocoumarins, vismiaguianins A and B were isolated from the CHCl3 extract of the roots of Vismia guianensis by bioassay-directed fractionation using the DNA strand-scission assay and KB cell line. Of the isolates obtained, vismiaguianone B exhibited DNA strand-scission activity, whereas vismiaguianones

Xanthones, xanthonolignoids and other constituents of the roots of vismia guaramirangae

Phytochemistry, 1983
Abstract A new prenylated benzophenone, vismiaphenone C, has been isolated from the root bark of Vismia guaramirangae together with the known vismiaphenone A, chrysophanic acid, γ-hydroxyferruginin A and γ-anthrone A 3 . The woody part of the roots has been shown to contain 10 xanthones, three xanthonolignoids and syringaresinol.
