Abstract
The chemical study of Alvaradoa amorphoides led to the isolation of four major constituents: chrysophanol (1), β-sitosterol (2), atraric acid (3), and 17-octadecen-6-ynoic acid (4). All compounds were evaluated on in vitro cytotoxic and antiproliferative assays. Atraric acid and 17-octadecen-6-ynoic acid showed cytotoxic activity. Additionally, compound 4 exhibited cytotoxic activity showing a certain degree of selectivity against cancer cell lines.
