Quantitative Determination of 18-β-Glycyrrhetinic Acid in HepG2 Cell Line by High Performance Liquid Chromatography Method

Figure 1

Chromatographic profiles of HepG2 lysates. In intracellular sample, incubated for 2h with GA, a signal that corresponds to a substance with the same elution time of GA was found (black); the described signal was not present in the untreated samples (pink). Inset: Intracellular GA amount.
