    Description: Vernolide B has marginal cytoxicity (ED(50)=3.78, 5.88, 6.42 microg/ml for KB, NCI-661, and Hela, respectively).
    In vitro:
    Chem Pharm Bull (Tokyo). 2003 Apr;51(4):425-6.
    Two novel sesquiterpene lactones, cytotoxic vernolide-A and -B, from Vernonia cinerea.[Pubmed: 12672998]

    METHODS AND RESULTS:
    Bioassay-directed fractionation of an ethanolic extract of stems of Vernonia cinerea has resulted in the isolation of two novel sesquiterpene lactones, vernolide A and Vernolide B. Their structures were elucidated on the basis of spectroscopic analysis.
    CONCLUSIONS:
    Biological evaluation showed that vernolide A demonstrated potent cytotoxicity against human KB, DLD-1, NCI-661, and Hela tumor cell lines (ED(50)=0.02, 0.05, 0.53, 0.04 microg/ml for KB, DLD-1, NCI-661, and Hela, respectively); Vernolide B had marginal cytoxicity (ED(50)=3.78, 5.88, 6.42 microg/ml for KB, NCI-661, and Hela, respectively).
