Figure 3From: In vitro antiproliferative activity of partially purified Trigona laeviceps propolis from Thailand on human cancer cell lines The decrease in the in vitro IC 50 values (μg/ml) on five cancer cell lines, plus the CH-liver and HS27 fibroblast normal cell lines as a comparative reference control, with increasing purification stages of the propolis extract from T. laeviceps. Data came from the mean ± 1 SD of percentage of cell viability which was derived from three replicates.Back to article page
