Figure 2.

Effects of the root extract at different treatment times on the accumulation of intracellular lipid. The relative amounts of accumulated lipid are shown as a mean value ± S.D. of five-replicate measurements for each period that the extract (100 μg/mL) was present in the culture medium. Asterisks indicate a significant difference at p <0.05 from the untreated control (0 μg/mL) at Day 8.
