Luteoloside inhibits proliferation of HCC cells.

<p>(A) HPLC analysis of the purity of luteoloside used in the present study. <i>Insert</i>: The chemical structure of luteoloside. (B)–(C), comparative dose- and time-dependent effect of luteoloside on the proliferation potential of HCC cells. The percentage of cell viability in different treatment groups was determined using Cell Counting Kit-8 assay. *, <i>P</i><0.05; **, <i>P</i><0.01; ***, <i>P</i><0.001; NS, not significant (<i>P</i>>0.05), versus non-luteoloside-treated control group.
