In vitro plant regeneration of Vismia guianensis through organogenesis

Plant Cell, Tissue and Organ Culture, 1999
A protocol for in vitro plant regeneration through organogenesis was established for Vismia guianensis(Hypericaceae), a species that produces an anti-cancer compound. The highest mean number of shoots per gram of callus (57.33) was obtained on Murashige and Skoog medium supplemented with 4.44 μM 6-benzyl-aminopurine, 5.70 μM indole-3-acetic acid and 12.

Vismiaquinone, a Δ1-isopentenyl substituted anthraquinone from Vismia reichardtiana

Phytochemistry, 1981
Abstract 1,8-Dihydroxy-7-(Δ1-isopentenyl)-6-methoxy-3-methylanthraquinone (vismiaquinone) was isolated from the leaves of Vismia reichardtiana. its structure was established through chemical and spectral means. A hypothesis for the biogenesis of the uncommon Δ1-isopentenyl side chain is presented.

Vismiaphenones D−G, New Prenylated Benzophenones from Vismia cayennensis^†

Journal of Natural Products, 1998
Following anti-HIV bioassay-guided fractionation, four new prenylated benzophenones, vismiaphenones D-G (7-10), were isolated from extracts of leaves of Vismia cayennensis. The structures were elucidated by spectral analyses. Only vismiaphenone D (7) exhibited HIV-inhibitory activity in the NCI primary screen.
