Extrapolated from dose-response curve. HT29 (human colon), A549 (human lung), PC3 (human prostate), MCF7 (human breast), Hepa1C1C7 (murine liver), and H4IIE1 (rat liver). GI50 is the concentration of an extract (μg) that causes 50% growth inhibition. TGI is the concentration of an extract (μg) that yields no net growth over the course of the assay. LC50 is the concentration of an extract (μg) that kills 50% of the cells that were present at the time of the addition of the extract.
