    • 2 for 4-7 days. After the cells reached 100% confluence, the culture buffer was changed to a differentiation buffer (150 μL per well) and samples that were dissolved in MeOH or water (7.5 μL) were added. Differentiation buffer was composed of DMEM containing 10% FCS, 1 μM dexamethasone, 0.5 mM 3-isobutyl-1-methylxanthine (IBMX), 90 U/mL penicillin, 90 μg/mL streptomycin, and 10 μg/mL insulin. As a control, MeOH or water (7.5 μL) was added in place of samples. After 7 days, the differentiated 3T3-L1 adipocytes in a 96-well plate were treated with 2% Triton-X 100 (10 μL/well) for 30 min at room temperature followed by sonication for 1 min. Fat accumulation was determined by measuring liberated triglyceride using a Triglyceride E-test Kit (Wako), and the absorbance at 630/690 nm (Microplate Reader EL-800, BIO-TEK Instruments, Inc) was measured according to manufacture's instructions. Fat-accumulation rate was calculated as percentage of the control. To determine the cell viability of differentiated 3T3-L1 adipocytes, another 96-well plate was treated with a Cell Counting Kit-8 Test (Wako), and the absorbance at 450 nm was measured according to manufacture's instructions. The viability was calculated as percentage of the control.
