Effect of (a) royal jelly (RJ), (b) royal jelly-water fraction, (c) royal jelly-ethyl acetate (RJ-EA) fraction, and (d) 10-HDA compound on the cell viability of 3 T3-L1 preadipocytes. Data are presented as percentage viability of preadipocytes compared with untreated control. The data shown are presented as means ± SD of triplicate experiments. Statistical significance was calculated using one-way ANOVA followed by Dunnett’s multiple comparisons test. *P < 0.05 vs control; **P < 0.01 vs control. Statistical significant difference between any particular sample concentration and equivalent DMSO amount of that concentration was calculated using unpaired two-tailed Student’s t-test. ##P < 0.01indicates statistically significant different
