Relative lipid content quantified via Oil Red O staining in 3T3-L1 adipocytes. Results are given as a mean value ± S.D. of six replicate measurements. Bar graphs represent the relative amounts of accumulated lipid in cultured 3T3-L1 adipocytes after treated with various GBR extracts in different concentrations. a-nValues with different lower case letters are significantly different at p < 0.05.
