Bioassay-directed fractionation of the bioactive alcoholic extracts of Vellozia candida yielded a new 6,7-seco-rosane diterpenoid, candidalactone (1), which showed moderate toxicity toward DNA repair-deficient mutants of Saccharomyces cerevisiae. Another new but inactive rosane diterpenoid, candidenodiol (3), was also obtained. 
In Vitro study of Vellozia pusilla pohl (Velloziaceae), a Brazilian plant species: antitumoral activity and labeling of blood elements
TLDR
The methanol extract of roots, stem and leaf sheaths of this species showed an antitumoral activity through the inhibition of the enzyme Topoisomerase I when analyzed by an in vitro bioassay employing DNA repair or recombination deficient mutants of the yeast Saccharomyces cerevisiae.
Structure Elucidation, Antimicrobial and Cytotoxic Activities of a Halimane Isolated from Vellozia kolbekii Alves (Velloziaceae)
TLDR
In the mechanism of cytotoxic action, halimane 1 interferes in two major phases of the cell cycle: in S phase, in which DNA synthesis occurs and where it is very sensitive to damage, and G2M phase which is the phase of preparation for mitosis and mitosis itself, showing apoptosis‐inducing properties.
