PU is the main active component of PE. HepG2 cells were treated with various doses of PE for 24 h. Next, we measured the cellular TG (A) and cholesterol (B) contents. HepG2 cells were treated with 10 μg/ml PE, 4 μg/ml PU, or 4 μg/ml EA separately for 24 h, after which the cellular TG (C) and cholesterol (D) contents were measured. HepG2 cells were cultured with PE, PU, and EA separately for 24 h during stimulation using 100 nM insulin, after which the cellular TG (E) and cholesterol (F) contents were measured. The values are the means±the SEM from three independent experiments; **p<0.01 versus the relevant control group. EA, ellagic acid; PU, punicalagin.
