- Abstract
Based on literature analysis of 308 angiosperm species inventoried from a 50-hectare forest plot on Barro Colorado Island, Panama, 40 species were selected and 80 samples (two samples for every species; leaf + twig and stembark samples) were collected for investigation of their medicinallpharmaceutical potential. Extracts of these 80 samples were tested in bioassay systems to assess cancer chemoprevention (eight assays), antiplasmodial, cytotoxicity, and anti-HIV activities. Details of bioassay techniques are described. Of the 40 species, 12 (30%) showed activity in one or more of the 11 bioassay systems used. These active species are Bombacopsis (= Pachira) quinata, Calophyllum longifolium, Casearia commersoniana, Lozania pittieri, Maclura tinctoria, Mouriri myrtilloides, Olmedia aspera (= Trophis caucana), Pseudobombax septenatum, Spondias radlkoferi, Stylogyne standleyi, Turpinia occidentalis, and Vochysia ferruginea. Because literature data on thechemistry of Bombacopsis (= Pachira) quinata, Lozania pittieri, Mouriri myrtilloides, Olmedia aspera (=Trophis caucana), Pseudobombax septenatum, and Stylogyne standleyi, are lacking, and similar data on the other six species are deficient, further firactionation and isolation work on these active species potentially may yield novel, biologically active structures. This study demonstrates that a plot-based selection of plant species for evaluation of their potential medicinal/pharmaceutical value has merit in achieving such a goal, and should beused in a program on plant drug discovery.
